I can't imagine ever going back to Maguras . I suspect a lot of riders fit Vees and reject 'em within a week , whereas I usually find that there's a brief period of " settling in " where the pads wear to the rim's surface and the cable and housing settle properly . Once correctly set up , presuming good cable , pad and booster choice the brake offers oodles of controllable power . It's ashame about the weight penaly incurred by needing an adapter for most modern 4 bolt frames , though . Strangely , I find that while choice of all the components are crucial to a healthy setup , the arms themselves seem to make little difference , like the fellow who downgraded to Promax ones reported . Shameless plugging of my Vees ( Deore arms ) on my new Karbon :
