Well, it's been six hours Jeff, and no reply.
I hesitate to inform cuz there is a huge tendency on MTBR for there to be a pissin' match between posters- far too much contrariness for the sake of- an epidemic of trolling rather than wealth of information available otherwise some high count regulars would have answered by now.
With the rant over, your shifters should be fine. Yes, they do wear out -some faster than others- but you should be fine sticking with what you have.
What makes a HUGE difference is having your cables and housing in very good shape. When these get worn is where you have a subtle increase in friction; every switch out to new and you get the (almost) new feeling back in your indexing shifts. If you have the cash to consider whether you need new ones or not, I would rather put that dough toward quality H&Cs. Maybe something with a continuous liner: ilinks, or Gore, etc.
This makes more sense in the effort and crispness you want as an on-going experience when you are riding.
I have many index shifters going on ten years plus (XTs use ball bearing shift plates, LX are just bushings, but if kept clean they will last quite a while i.e).
