I usually run the original 550xp and also use a 261 v2 quite a bit, but i recently tuned-up a buddy Stihl MS250 that had a ton of compression, cut real well, and felt much lighter than the 550 or 261, specs say the MS250 is 10.1 lbs, maybe it holds less gas/oil, plus it had a 16" bar, but it was a lot of fun to cut with, wonder what a ported one could do, i did notice the anti-vibe wasnt as good though
