Hi all. So i've been chainsaw milling for a few years now, i have a 395xp that is my regular use and i just got a 3120xp that i'm still working the bugs out of. usually using a 42inch bar and sometimes for larger logs i've put the 62inch on, i always use an aux oiler. I'm currently in Hawaii and i've mostly been milling monkeypod, mango and lychee. So i've used lots of different ripping chains, from oregon, stihl, carlton, forester, archer and a few others. I haven't used the grandberg chain yet, just cause they cost so much. Are they worth the cost? I'm getting pretty good a sharpening and keeping the rakers at the right height. So what's your opinion? who makes the best chain for the money. will a grandberg chain stay sharp so much longer than an archer chain to justify the extra dollars?
