Whistle Stop is correct. You might be better off trying those (name escapes me at the moment, check out a supplier like Stew-Mac) banjo tuners with adjustable presets. I like the Hipshot too, though I haven't got one, but you can't replace all your tuners with them because they won't operate with hardware on both sides of them, unless they've re-engineered them lately.

If the weight of more hardware at the end on the neck becomes a problem, do what I do and replace the tuner buttons with much lighter (and classier) ebony or faux pearl buttons.

Mooh.
