Regular
This is the original G-String yoyo string format. Super soft on the hands and will significantly reduce string burn. If you are looking for the softest G-String yoyo string that is still playable look no further. The Regular format, due to it's longer length and overall softness when compared to cottton/slick strings, is a favorite among 4A players.

Team Member thoughts on Regular Format
Bryn - It gives a really cool "gliding" feel when going through tricks and is hands down the softest I have ever felt. The softness reduces confidence in holding formations at high speed and I found knots were a bit difficult to remove.
Stefan - While some people might like the softness, I really didn't like it that much. It also felt a bit slow to play with (1A). It's pretty good for 4A though.
David - Super soft. Lasts long, like all the other string, but not quite as long as Intentus. For my needs, it's a bit thin, but I am weird and enjoy really thick string.
Palli - By far the softest format, even a little too soft for my personal prefernce. It plays the slowest of the formats which is good for slow slack play(often seen by brazillian players).

SSE
SSE stands for Slack/Suicide Edition. This format uses my 'D2' twisting method to create a G-String yoyo string with a tension perfect for Slack and Suicide play. They start out a bit firmer but soften up while still maintaining the SSE level of play. SSE is available in all of my current designs.

Team Member thoughts on SSE Format
Bryn - This stuff is REALLY great for slacks, whips, and suicides and it seems that with increased play, the string required a bit more tension adjustment.
Stefan - Probably my 3rd favourite format for 1A. It held it's shape well, and was definitely firmer than Regular.
Palli - Soft and hold slacks, whips and suicides really nicely. An all around good string and just feels right.

TH
To provide those players who enjoy the SSE format, along with the tension and playability it provides, with a G-String yoyo string that will hold itself together during play while not requiring a huge bearing gap to accomodate extra layers of string. TH is 'THinner' than my other G-String yoyo string formats. But don't let its overall thickness fool you. This format will still outperform your expectations. If you prefer a gap that isn't "shimmed-out" wider than a 4 lane highway I suggest you give it a try. (The TH format may vary slightly from the catalog image as it uses a variable run count depending on design.)

Team Member thoughts on TH Format
Bryn - A very quick string that is easy to manuever while holding complex formations. The visibility is a bit down compared to other formats, but producing it in solid colors would help alot. With increased string tension, it felt a bit wirey running across my fingers.
Stefan - If Intentus is my lover, TH is my thing on the side. It has a really different feel to any other string I've played and it's really refreshing and fun. It lowers response too, which could be a plus depending on how you're looking to play.

PX
This is my favorite format for out-and-out fun yoyo throwing. Inspired by a custom request for something similar to the 'rope' that some Polish players have used. PX is a thicker string overall. It performs slacks, whips and suicides with ease and is massively visual all at the same time. If you are seeking a string that will hold up to anything you can throw at it, never lets you down, and can be seen for miles...PX is for you. (The PX format may vary slightly from the catalog image as it uses a variable run count depending on design.)

Team Member thoughts on PX Format
Bryn - Great visibility to both player and spectators. Slack appeal of SSE in addition to confidence in holding formations. Although this string is a bit slower moving when compared to other string formats, playing with PX is..."fun".
Stefan - For 4A this format has been a revelation! Nice and long for more spin-time. Thick enough to make 1 string whip returns much more reliable, but doesn't snag on regular catches or anything like that. Very nice.
David - Probably my favorite string type. Really thick, feels kind of like a softer, thicker Intentus. Lasts forever.
Palli - It has the smoothness of the SSE but is fast like the intentus. Thicker than the other formats which can be interesting on some smaller gapped yoyos.

Intentus
Intenus utilizes a whole new twisting method I call 'CORE' to create a super 'core' string with a slightly smaller overall diameter while still utilizing a 'strength-reliable' thread count. It was designed for those players who prefer even MORE tension on their main players while still enjoying the visual aesthetic that G-String provides. The slightly thinner diameter also caters to a smaller gap for multiple layer tricks.

Team Member thoughts on Intentus Format
Bryn - My favorite string format by far with great tension and it feels cool moving across fingers/works well in humidity. Easy to hold, and transition between formations and sadly I will never have enough of it. People are still using YYN Highlights while this is out?
Stefan - LOVE! Nice and firm/slightly rough to begin with, then as you play it gets even better! Holds slacks and suicides very nicely. Definitely my favourite.
David - Wound really tightly, which makes the string really palpable when doing slack tricks. A bit rough for my taste, but overall, really well rounded.
Palli - This format plays really FAST, it makes lacerations,whips and suicides even easier to do than on SEE. The downside is that it feels a little rough for me.
