When you take that tone--that "um, no" tone--and you're so clearly wrong you're not really shown in the most flattering light. The Beal Joker, PMI Verglas and Fusion, The Monster 7.8, the Tendon 7.8 Master, 8.5 master, and 7.9 Ambition can all be used as both half and twin ropes. So... Um, whatever. Using half ropes as twins defeats the entire purpose of using half ropes, as twins are not nearly as accommodating to meandering routes, and clipping two half ropes to a single piece increases impact forces in the event of a fall... using a triple-rated rope like the joker as a twin is like---> joke's on you! --> at best, if you need the redundancy of an additional rope, clip it as a half-rope. OR, even better... just purchase the right set of half-ropes the first time. it's probably cheaper than a pair of jokers, and just as effective.
Gotta go with Sty here. In fact, the whole idea of twin ropes is really just stupid. Single rope failure is essentially nonexistent for all practical purposes, so if you're going to limit yourself to a single rope path, go with a single line.
If you're going up there with two ropes, get halfs. it will help mitigate rope drag issues, and won't give you the double impact force/greater equipment requirements (more biners) of twins.
Single lines or Half lines. There's really no need for anything else in climbing.
