I know that it's down to personal preference but some pointers you might still have. I've got some money to spare and want to buy a new frameset. How does the Arcade compare to my 2012 4play?
Geometry (4play) Wheelbase: 1020mm Chainstay: 375mm BB Height: +25mm Head Angle: 73˚
Geometry (Arcade) Wheelbase: 1000mm Chainstay: 364mm BB Height: +25mm Head Angle: 74,5˚
My 4play bunny hops rather well I think but I don't have any comparison as I haven't ridden any modern street trial geometry yet. What I currently focus on is spinning and front wheel moves and bunny hops (of course). I know that riding wise, I haven't reached the limits of my current bike yet, nor will I ever do but I would like a change. Still, I may profit some of a new frameset.
And to make things even more difficult, I really like the new TMS Silex:
Geometry (Arcade) Wheelbase: 998mm Chainstay: 350mm BB Height: +22mm Head Angle: 74,5˚
