classics slappy well, but if i put in too much energy they tend to slip out
conical fulls (mine used to be 58) were best for slappies, but the smaller and more square they get the more you have to push (or increase the angle of impact, so it is easier to ride up the curb)
lock ins i imagine to be perfect, because the outer edge is round enough to slappy but lock in on top of the curb.
tablets seem shit but i can't confirm
