May I ask why the need to ridicule someone doing something different? If he tries and fails, so what? He is only asking experienced folks for advice, and many gave it.
I ride single speed, and am doing my first single speed "tour" this year. I started a thread with a question, and specifically didn't mention the SS part because I didn't think folks would get past that and answer the question. This OP asked specific questions, and seems to have taken most of the advice given as to gear selection. Would I try the ride I have planned for me fixed vs SS? I would not. That doesn't mean he shouldn't. At least in my opinion.
