I agree with you about loving acrylic. I also hate ebonite and the maintenance. Some think it is too hard, but I appreciate that as I am a clincher and tear up ebonite quite often. You mention Petersons, I think you pick the lines with acrylic. Peterson's often use Vulcanite, which I also avoid.
Yes, historically you had to be a bit picky with Petersons if you wanted acrylic, as they only had a few lines that used it on the stems (e.g. Rosslare, Royal Irish, Flame Grain, etc). But lately it seems like they've started using acrylic more broadly, and these days you can get most of their pipes (including Systems!) with acrylic stems.
