I like cantis. Easy to set up if you have the knack. You can set then up for power, or sacrifices bit of power for better feel and modulation.
V' s aren't any better than properly set Canti's, just easier for the spodes of the late 90s to bodge into working order.
Have to disagree with you there - the longer cable travel (and therefore lower cable tension) of V's reduces cable losses from friction and compression of the outers. Also, leverage does not decrease with travel with V's - cantis decrease in mechanical advantage as they get closer to the rim (as the straddle wire becomes more of a 'V shape').
However, I do agree that well-set up cantis work perfectly well, with most of the problems being due to a lack of mechanical sympathy. The final generation of low pro cantis (1992 on, not Grogee's type above) were a step backward from the older wider types, with the mechanical advantage changes being more severe.
V's are awfully nasty at being more grabby and not at all progressive...a problem of all that mechanical advantage!
Ride it or milk it!
