Interesting thread for me, as I own two 056 Mag IIs, and only just this week picked up an 064. A bit late to weigh in with advice, but I think you made the right choice with the 064... even though I absolutely love my 056s. The main problem with the 056 (as already mentioned) is parts availability, both of mine really need new mufflers and I've been having to patch the old ones up, or even fabricate one. The other is the weight - I used my 064 yesterday and it's certianly a lot lighter! Another thing with the 056 is lots of vibration... make sure everything is done up tight! On the other hand... after using my 064 yesterday, I can say without doubt the 056 has way more torque, way more power. Having said that, the 064 still has enough power for my needs. I was thinking of selling my 056 Mag 2s (including an incomplete 3rd one for parts), or possibly even part them out - but I suspect I would regret that in the future. I might just hang onto them I think.
