I'm using the Marineland sleeves in a u-size as well. Bought a pack of three at my local pet store. They wick amazingly, but after a few hits I start to get a plastic/synthetic taste.
Maybe I need to try a PV that doesn't run as hot as the 510. Any advice on another model? I really like the hit I get from a 510, but am noticing that it does seem to heat up the various cart fillers I have tried. I've even tried three different attys, all the same result.
I've heard good things about the 801, but don't own one. I really don't want to dump the $$$ into a Janty stick or SD.

You could try one of the sub-90mm models like a 403, an 8084, or an L88b (I use a blu, which I know has a poor reputation, but it's actually very capable for such a small device if you treat it right), but I think you'd look at it as a major step down from the 510.
