When I first starting sport climbing I wasn't sure which quickdraw to go with given the many options avaliable. Then I climbed with my buddy who had a set of LiveWires. As soon as I got home from that trip I had a set of 12 in the mail coming my way. The thick dogbone makes hitting those just out of reach bolts a snap. The upper Dynotron biner is very smooth and easily slids into place on bolts. The wire gate is smooth but provides enough resistance to feel confident once you have the rope in it. They may weigh more than other biners but if your saying the weight of your quickdraws is preventing your sport ascent your pulling at excuses! Hands down the best quickdraw out there. The saying is true, you get what you pay for.
