My thought on the issue is that everything gets wonky when you allow attributes much over 15, IME. I think if you reworked the calculations for BL so they were less finely granulated and put the vast majority of humans at 15 or under on all four attributes you'd be pretty good.

So anyways, my solution is make ST 20 as far outside realistic human norms as IQ 20, refigure lifting and carrying capacity to line up with a general max of roughly 15 for people who aren't Andre the Giant.

EDIT: Oh, combined with a rule that gives all melee weapons skills a bonus to damage a la Karate/Boxing at higher levels, and further nerfing of standard weapon damage. So a skilled strong warrior can do some damage, but a peasant with a spear is unlikely to do much unless he gets lucky on the hit location/critical table against anyone reasonably prepared.
