I'm a big Elixir guy, usually putting 100-45 nickles on all my basses. I can easily kill normal strings in one 3 hour gig and Elixirs have been a life saver for me. However, I had some SS Elixir 105-45 on my 4H Special and did not like them at all. They had too much boom and sizzle and lacked what I perceive to be a fullness or evenness of tone.
I actually put some new Super Slinkys back on my special and think that they are the best match for the Stingray, go figure. The tone and feel of them on the SR might be enough for me to just bite the bullet and change strings more often.
I have found the Elixir nickels to have a fuller tone. Haven't perceived boomy in the past or on my 30th SR5 with the stainless, but they certainly have a different sound and are not as full as the nickels.
I thought about running Slinkys after playing them when my last couple of new basses arrived. I liked the tone, but I'm stuck on the feel of the Elixirs. And, like you, I kill normal strings very quickly and would have to change strings quite often.
