Started playing yesterday with the Singlecut which has a flat radius. Things were alright but the fingers got tired rather quickly after a legato workout.
After the break, the Strat took over & the fingers felt more relaxed, there were less mistakes.
Implication: Flatter radius does not equal easier playability. Yes, there is a fair amount of ease when one plays with a flat radius. The action tend to be more uniformed across the fretboard but that does not always translate into a preferred playability. The flip side of this is of course, our playing style, particularly how we posture our fretting hand. Personally, if I am focused on rhythm & riffs, I'd grab a flatter radius. 😁
