I feel the need to chime in as a fellow FZ1 owner, those monoblock calipers are slick, aren't they?
I'd say make sure the pads on your 7200 are set up properly first. Adjusting pads on canti and V brakes seems to be something of a lost art and if done wrong can absolutely ruin the brakes.
I had some bad experience with the stock brakes on my Kona cyclocross bike- I swore I'd get discs on my next bike. Last season I took the time to replace the pads and install them properly and now the stock cantis are more than capable of locking up the 35c tires. There's no way I'd run discs on a cross bike now.
There's a relation between your weight, the size of the tires you run, the surface you're on, and the power of your brakes. Make sure it's all in balance.
