Clamp on v brake adaptors are fine. I have mine for about 8 months now, no problem with them and there are quite a few other polo players who runs them too.
The adaptors are designed for 31.8mm (1 1/4") forks blades but you can easily shim them to fit 28.6mm (1 1/8") ones.
You might be able to use clamp on canti bosses on those forks.
is this a good idea? opinions that ive seen on it usually seem a bit torn between "yeah its fine" and "DEFINITELY DO NOT ELSE YOU WILL DIE"
i may just have some brazed on eventually once i start running it singlespeed
