I have several bikes with different brakes. My biggest concern by far is locking up wheels and control issues in hard stops. I will take less power and better control every time. I may have to change my ways as I get older and lose hand strength and cold wet days with long descents have been a challenge but I am still liking my two dual pivot brakes de-powered with V-brake levers. (A different modulation - excellent wrt stopping vs hand pressure but the levers don't move!). I also like Mafacs and regular Tetro road levers. Very different feel but except the feel, I get no surprises going from one to the other. And my Mooney's circa early '80s Shimano OEM cants just strike me as "right" every time I use that bike.
(I never liked the dual pivots with regular levers, what was supposed to be the holy grail of the braking experience. Always felt like a crash waiting to happen when I had my guard down. By contrast, on one of my first rides with the V-brake/dual pivot setup, I rode fixed down McKenzie Pass, coming into a steep blind corner way too fast, grabbed an handful and promptly blew off a lot of speed. Nothing else happened! I was sold.
So, for me, V-brakes are probably a long ways away, but I do like those V-brake road levers. (Another plus - they make wonderful, huge hand holds for out of the saddle climbing; great for big gear climbs.)
