Sugoi are comfortable but I find they don't last that long. I've had allot better luck with Rapha for comfort and durability, worth the price in the long run.
www.rapha.cc - you can find sales for them as well).
I've also noticed that the Sugoi stuff does tend to wear out faster than the rest of my bibs (castelli, capo, assos, and PI). The material stretches and the chammy gets harder than the others, causing saddle sores. The 2010 and 2011 versions were more cloth-like that wore out after about 2 years worth of riding (4-5k miles/yr and washed after every use). The 2012 versions were substantially better, but they had a more lycra feel (I liked them better) and they're seeming to hold a little better in terms of durability.
