I think if you look around, you'll find Shimano has more of their tech documentation online than any of their competitors. So if you're not satisfied with Shimano's approach, it's unlikely you'll be happy with any alternatives either. When the time does come to replace drivetrain parts, I'd suggest the Salsa aluminum chainrings (nice 7075 aluminum) and changing the rear hub to a 7-speed Hyperglide setup, then tracking down a set of 7sp XT or Deore thumbshifters (or at least the right side). Then you'll be on a sustainable platform.
