I recently upgraded my Dean Evo.
After some research (of corse after i bought everything) i found that Grover has 18:1 tuners. I have the 14:1 one mine.
Is the upgrade worth the extra cash? (Will be selling the old ones)

Also i just have a black wraparound tailpiece

Is it worth it to upgrade to the TonePros model? NEW BRIDGE

(will probably setup the intonation as the same as the old bridge)
The ratio just makes it slightly easier to tune it precisely. I wouldn't waste the $80 or w/e on tuners if mine were fine.
