Paper is right on if you're talking different lengths. If you mean the torsion spring like the one in the pic, it is a better option in that you won't need to ever think about it again, but requires drilling and a bit more effort to get it on. If you got the torsion and aren't worried about a challenge, go for it. If you're talking length, listen to Paper.
