nope, i would stay well away from parrallel push vee on a trials bike (or street too), the linkages go very wobbly and make the brake feel horrid. dewhore arms are fine and just as good as sd7s really. Ultimates are amazing. Wiggle are doing a pair of sd7 levers for £20 at the mo, so you could still have matching levers Even deore levers are decent http://www.pijin.co.uk for cables as its free postage LIES!!!! I am not having a go but it really doesn't. Good pads and a grind will give as much (if not more) power as a maggie, with the same pads and grind.
