My advice is, if the Butler Creeks work for you, keep on using them.

For me, the new production ones don't work. I've not had a problem with my older set, but the newer ones I've had don't hold up for me. This is a very common issue that's been discussed on many sites, including Opticstalk.com, Snipershide.com, etc. So for the ones of us who keep breaking them, we obviously need to find an alternative. Just because you haven't broken yours doesn't mean that we are having the same luck. No need to come in here, post after post, bashing people who would like an alternative.

If the Butler Creeks work for you, that's great.
