MTB Chainset Choice

Hi,

I need to get rid of my chainset sometime soon (c.f. previous threads, worn
rings, bolts, ruined thread), and I was considering putting the 2003 XTR set
on.

I've been reading nasty things about bearing wear on it, which concerns me,
because I'm a very heavy rider (both in weight and abuse). I quite like the
look of the XTR crankset, both in terms of aesthetics, weight and design,
but I can't be dealing with BB bearings wearing out in a matter of weeks.

Might I be better to go with something like the FSA carbon series? The price
seems relatively high even compared to XTR, by the time you factor in BBs.
Mind you, it might be recouped by the time I come to replace my first set of
chainrings

Any advice or experience much appreciated.

John
