...and for all but the best of the best, there will always be an opportunity to tweak technique for far better gains than gains on equipment...granted one is on a high quality product. Not to say that equipment changes can't help us all to a degree--particularly if our technique is what it is--and more difficult to manipulate for a variety of reasons--tweak the equipment for the technique embedded.
For most--I suspect there are some nuggets on technique that would yield larger gains. For those with excellent/reproducible/consistent technique the equipment tweaks are more important. It's cool to see the envelope pushed both on technique and equipment.
