Trials stems are wierd... I see what you are saying with the HT angle... i think the 20" bikes would suit a taller steerer and a short bmx style bar. Having your steerer(bars) be a 4" radius from stem or so away from the stem does compromise certain moves and more so handling in general. A steeper steerer and shorter stem will defiantly give you what you are looking for. Ive always seen inspired bikes as 24'' bmx bikes with disc brake mounts so maybe try a bmx geo(with slightly higher bb) with postmount tabs from marino and see how it feels. I feel like the stem / bar is really what needs to be figured out.

Marino can make them as well. http://marinobike.com/order-form/ however, at only 250$ for a custom frame i doubt the tubes are double butted.
He is just riding alot more tech stuff now it seems. He still has good style hes just not doing huge drop gaps and pallet gap max training. Seems to be transitioning into a more comp style rider than TGS.
My tensioners are all the way out and my new KMC Z610 HX, 3/32" is 3-4 mm to short and if I add two more links its too long... Right now Im using my friends old chain and the only reason I think it fits is because its been stretched already... Will I have to use a half link? or should I try a different chain?

I rode a similar bike(tank) for a year or so, which I payed 250 USD = 175 euro?? It WILL help you learn the basics of throwing your weight around the bike, its still great fun and gets you past the most difficult part of the learning curve...
