Why is a 1wt more popular than a 0wt or 00wt? I may be wrong but from what I hear from the board I haven't really heard of many people using 0 or 00wt rods...just 1wts. Also doesn't seem like a 2wt is vary popular either. Why? How much more can you do with a 1wt than you can a 0 or 00wt? How much different is a 1wt and a 2wt?
