I've finally reached the point where I'm ready to replace the 17 year-old cantilever brakes on my bike. I definately want V-brakes but I don't know how much difference brand and level makes. I've been looking at Deore calipers and levers but haven't looked higher than that or at other brands like SRAM or Tektro.

Any recommendations on a specific set? My primary motivator is easier adjustability but I also prefer the greater stopping power and smooth feel of V-brakes. I'm a large clydesdale (350 lbs) and my riding will be all in dry conditions, pavement and hard packed earth.
