Anecdotal, having never put flats on a tele...

Had a set of stainless flats on my #1 Precision for 20 years before taking them off.

Granted I installed the EMG's on the same day - KahWhump.

Have a Taylor 810 that got fed a steady diet of .15 flatties for years - channeled Lowell with ease.

Now I'm squirming like a toad...
