The clear ones will last slightly longer, but the important part is the seal and how it fits the tip of the bolt. Just find one that has a good fit on the bolt tip and put it in, your problems will be solved.

Don't use the clear orings. Use the green or black orings. A brand new black (buna) 17/70 or 17/90 oring will fit the tightest. The clear (urethane) orings will fit the loosest and that is not good in the sft oring groove.
