I'm looking to get my first trad rack this spring/summer. I already have a set of nuts and hexes. I'll probably add a few tri-cams and double the mid-sized nuts. But I'm really curious about cams.
What are the essential sizes for a beginners rack? How many do I need? Should I double the mid sizes or just get one of every size. I'm guessing that for starters I'll leave out cams under 2"--the nuts and hexes will cover that. I'm also guessing that the biggest sizes aren't initially crucial. Also, what brands do people like?
