I suggest going to MTBR... www.mtbr.com and reading the reviews if your going to put alot of thought into getting a tool. I have a PARK MTB-1. One side has a chain tool and wrenches and the other side has allen wrenches. The side with allen wrenches is too big to get in almost all places, so i have a cheap GIANT allen wrench tool. I carry the side of the park tool with the chain tool, and the giant tool with me. I would suggest getting a cheap allen wrench set, usually their only like 8 bucks, and getting a park mini chain brute. But like i said, go read the reviews. Later
