I'm considering one of these saws since I'm in the market for a 60cc saw. Couple questions here. I've heard some starting or idilling issue with the 357xp. True?...maybe fixed if buying a new saw? That may have been early on...hopefully? The 357xp seems a bit more tested since it's been around more. I'm aware of the specs on both, so I'm really just looking for thoughts on both saws. I also noticed that the 562xp comes with autotune and xtorq. Are these features proven or more problems than they are worth. Lastly, this is sort of unrelated, but I noticed these saws will come with 3/8, 0.050", full chisel chain. I assume one would notice a difference if I normally used a .325, 0.058", full chisel..........assuming the same saw....and it was possible. I know this is a hard comparison, but I'm wondering what type of performance difference you see if everything else is created equal and you go to a 3/8, 0.050" chain. Thanks.........everybody is always very helpful!
