Jake - I didn't even run one until a month or so ago.....I was thinking I'd like a 1.5:1, but I really like the 2:1 that we got. You get used to it pretty quick, and it's a lot less turning of the wheel - which you do a LOT in short course!
we use a cheap $100 latest rage buggy rack, hard as hell going slow, but full lock is 90 degrees on the wheel for each direction, would work great with the unisteer.
