Ultimately, it is an individual decision that you will have to make for yourself...based on your personal preferences. I read all the PM2 love, and wanted to experience it for myself. Bought one, and didn't like it. I wanted to - I recognized the quality, the way it fit my hand, and the flat ground blade - but I plain ol' couldn't make myself. Time went by, and I tried another...and still didn't like it; but I recognized that it was an issue with the scales. Eventually, I bought another, and immediately put aluminum scales on it - and liked it enough to put it in my pocket occasionally. Earlier this year, I bought one in s110v, and put wood scales on it. A short time later, and it seems like ages since I have touched either one.
I have an 0560, as well - it is a very different knife as has been said. It is noticeably larger and heavier than the PM2. The blade is thicker, and not so much of a slicer. I like it much better, and have carrried it much more than the PM2s.
