Someone (me) needs chain sharpening lessons. Lmao. I watched hedgerow run saw 2 with a 32" bar and saw saw 1 with jacked 28" and a good 24". Not sure his opinion but it will pull a 32" but I would say the 24 or 28 combo is where it's at for this saw. I have 1 more saw on its way to throw into the mix I am going to put 103 with 30 bd in it and compare. Drop saw 2 to 105 with 28 bd. Depending on what I see there I will decide what works best for me. Then I will play with advancing the timing just a bit. Then we should have some final numbers. But i agree with hedgerow. I would not be afraid to send either of these saws to a customer. Unless there gonna run them against hedgerows 7900. Lol.
