...and I'll tel you why. Elixirs last a long time, but they are way too trebley and brittle for me, and don't really seem to have any mid-oomph. Bass players need that crucial midrange quality, if you want to make the lower frequencies really growl, and Elixirs just don't have them. Plus, they don't stay in tune that well, unless you have a graphite neck, or a really strong wood one.
DR Lo-Riders, if I only had a choice between them and Elixirs, I'd go with the DR's. I don't know if it's because I play with a heavier attack than most low-action bassists, but DR's die out within a few days for me. Every other factor in the Lo-Riders, triumphs over the Elixirs. The DR's stay in tune and intonate well (no coating interfering-this helps), no shedding of coating, but most of all, the sound is there. They do eat your frets a little, too. DR says they don't, but any stainless string will over time, whereas nickel is very easy on the frets, but doesn't sound nearly as alive. These strings have a nice stiff, but pliable feel, too. Lo-Riders are a very solid-sounding and evenly balanced string, but that sound only lasts a short period of time. They're grat for studio time, if you're not planning on being there for long. It's a trade-off, really.
I'm an extremely picky player, when it comes to string preferences. I've tried just about every regular and uncoated string out there, and my opinion, the absolute best string brand you can buy, is FireWire. They're from Canada, and they make a string that lasts as long as coated ones, but it's not coated. Their website is Link Removed, and you can only get them directly from the company, or a few dealers throughout the country. They're pricier than Elixirs and most coated strings, but totally worth it. I hope they take off, as they're a small company, but very friendly, when it comes to comments/gripes, and special custom sets.
Lastly, my opinion for the most badass and longest-lasting uncoated string, goes to La Bella Hard Rockin' Steels. Oh, and La Bella doesn't have that quality control issue anymore, that supposedly they use to. I've yet to find any flaws in my sets. I'm posting another thread about these, under the column about what strings we use, and I'll talk about FireWire, too. I hope this helps you weed out the junk!
