Cheers Dyna,
To be honest, it's my cousin who's asking, but he's not on any forums! However, I'm using XT M765s (just like Saint M800s) and find them rubbish compared to his Tech M4s. They used to be really good though, so maybe I just need to rebuild them. I find there's more lever feel to Shimano brakes then Hopes, which seem a bit on/off to me.
