My UL arrived yesterday and I already put whoopies on it for my first mod. I'm thinking about putting an adjustable ridge line (whoopie on one end) on it. I've done some research and found that some people comment that a ridge line actually doesn't work well on an UL. Is this so?

For those who do have one, how do you like it? How much of a benefit is there with the additional sag that it provides? Also, I was wondering what length of a ridge line should I be aiming for?

Thanks in advance,
