Well Mr. genius why don't you define 'light BB for us', and just why light means trouble? Would that be one with a Ti spindle, or a light one with a cromo spindle.Or maybe it's the difference between a 173g DA and a 250 g 105,both octalink, both with pipe billet spindle. Is a Record at 190g, a worse bet than a crappy SC-s at 358 g? Don't hold back.Inquiring minds need to know.
