My beloved 1.0 double WBBB scraped a concrete patio and endured a small tear in both layers, which quickly developed into a large tear in the outer layer. So, I need to replace it for sure.
Question is, should I get a double 1.1 or single 1.7? I'm a backpacker, so weight is of a concern. The 1.7 single is 1 oz heavier, but that's not enough to rule it out. Is this just a matter of preference, and if so, why would a person prefer a single over a double or vice versa? Oh, also, I'm 6,1 190lb, and I use an UQ, so slipping a pad inbetween the layers isn't important. Thanks for the input.
