By bigger do you mean wheelbase length?
And the change in bottom bracket height's pretty steep, have you tried any other frame with a similar height? The higher the more stable when hopping on the rear wheel and theoretically helps with gaps, sidehops but won't feel as good for rolling moves. So you'd probably feel a pretty big difference between those frames.
Also I've only heard good things about the Speedrace Fans frames and they look awesome in person, just throwing that in there
