I'd rather have 1 Busse because I probably wouldn't be carrying a spare if my lesser blade failed. What good is an extra cheap blade when you don't have it on you and your primary fails in the field?

I understand most of the time you won't have to truely depend on your gear, but someday we might all be tested and when that day comes I'll have the best gear I can afford, a well conditioned body, and hopefully skills and knowledge exceeding them.
