I agree with all the above, except the tightening the screws. If you tighen them too much
and your case is a smidgen smaller than it should, I've heard of the ball being pressed down by the top of the case, stopping the ball from rolling freely.
I don't have the happ 2 1/4", but it does look better than the suzo 2 1/4". Over three times better (price difference), I doubt, but if money is no worry and space is tight... [shrug]
As for the 3" TBs, I like the happs TB a little more than the betson, which I like a little more the the wico. All are good quality stuff, and I'd be happy with any of them.
And to repeat, lube the bearings! Then break them in some. (
