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!
