I've used the Cycra pro bends before too, and I had problems with cables and stuff as well with them.
Before I had the Cycra's I had a pair of the moose ones with no bend in them, and I would constantly have one come loose and spin around (you'll know what I'm talking about if you've hit the ground hard or something and they twist out of place) or something always going wrong.
On my 250 last year I used the Fastway F.I.T hand guards, that comes with the top bar mount that you bolt them too, they worked great because there's no way for them to really to come loose and spin, BUT the only issue I had with them is after one good wack, it actually twisted the metal, and after alot of tugging and clamping in the vice to try to get it back to normal, it was always a little tweaked and I had to run my front brake lever in a position I didn't really like because of it.
And like I said, I'm trying out the MSR hawkins hand guards right now, and fitment was the best I've used so far and the roomiest ones too! I'll know in the long run how they hold up.
