I have the EXPs on my LP right now but I've never used the Elixirs so I can't really make a comparison. The EXPs are very slick feeling and I'm not so sure that I like that. So far though, I've had very few issues with them which is good because the acidic qualities in my sweat tend to destroy strings rather quickly. I'd say that I have 30+ hours on these and they're still going strong.
