+1 I have V-brake on the rear of my tourer with a brake booster, and it has as much stopping power as the 203mm front disc. I went to the disc to avoid a possibility of overheating the front RIM on long downhills towing my trailer, not for more stopping power. The V-brake I took off the front was as powerful as the disc (with the booster).

I also use the salmon Koolstop pads.

BTW what is the part number of the long-pull Tektro's? I have R200A's and had to use a travel agent on the V-brake, so it would be nice to have the option of NOT having to use one.
