I think the bearing proponents are well represented here ta0, no need to refute my silly principles.
I can only think of two others that would maybe agree with me on this anyway.
I can't help it though... why spend all that time to weaken the top and limit it's trick-ability? Also, roll staring a big top is far, far easier and safer than a boomerang. Once you learn both of course. In this case, a Columbian style top I presume, yeah go ahead and stick a pair in that sucker.
