Using a Wittner tails piece with built in fine tuners might just do the trick for you. As it would leave full after lenght and easy tuning.
As for Prefection tuners, I love then. As a aging violinist it gets hard with time to turn those small screws.
Buy with the wittner tail piece costing about 1/3 the price of the perfection tuners. I think the wittner is a better choice.
With violins there is no fretting over the music.
I would also add, if your violin is not new-ish, the peg holes might be reamed out a bit. The perfection pegs might not fit properly unless the peg holes are "resurfaced". Not all peg holes will have worn the same, so its possible you might have to mix/match the 2 sizes they come in.
I can see a need for them with some arthritis or weaker hands. At this point in my life, I'll stick to just using friction. I only have 1 fine tuner on all my instruments, except the electric. It might be a skill set lost sometime not to far into the future.
