really difficult to do Smith/Feeble grinds

When trying to do a smith or feeble grind the game will automate the trick into a crook, blunt, or nose/tail slide.

I think it would be better if you were able to do something like pressing R1/RB to activate technical tricks, this could also open it up so if you press the bumper and than do the same movement for a crook, it would make it a smith. 

This could also open the game up for more flatground tricks, or even some freestyle stuff. Smiths and Feebles are my favorite grinds to do in skateboarding games, and currently their almost impossible to do even straight rails, stair rails are just not physically possible. The only way I've been able to do them are either on accident, or doing a 5-0 and pointing the nose down, but this is very inconvenient.
