Shave the weight off your quickdraws without losing out on performance: put a strong, robust straight-gate Shadow 'biner on one end, a big, lightweight, easy clipping wiregate Spectre 2 on the other. Sport climbers prefer the rugged reassurance of a krab which can take the repeated punishment of falling on bolts; trad climbers tend to go lightweight because of all the other gear they carry. Loads of people climb sport & trad though...so DMM put a solid sport 'biner one end but made it nice & big for use with gloves, & a lightweight wiregate on the other: how many sport climbers wouldn't appreciate the super-fast clip of a wiregate? Both the Spectre 2 & the Shadow benefit from strong, light I-beam construction & a nice deep rope basket, & are racked either end of 18cm of 11mm dyneema. Simply put: a great all-round quickdraw.
