I can’t even start to think of two handed string tricks the whole time I’m just trying not to hit myself or get a knot. I can’t imagine doubling the amount of things to hit myself with. XD
I believe it’s been done, I think I’ve seen Stephen Langley do it last week end at EYYC (I remember seeing 2x4A throws in motion at some point)
most of the stuff has been done, 4A with CW, 3A with CW, 2A with CW, 5A without CW, 2 yoyos on the same string, 2 yoyos in the same hand etc…, tied string (regular 1A) with sliding CW, moebius with CW etc… etc…
the style is called 13a . 2 5a yoyos plus the 3a style = 13a. i have been working on this style for a couple of weeks now and love it. i am a 3a player in general but dont know very much 5a. this way i am improving my 5a skills at the same time. i highly recomend more people try it. it is kinda hard but very fun. i have made up a bunch of tricks already, it seems with 13a the possibilityies are endless
