When it comes to saving your back, here is a logger trick that always works...get the longest bar you can for your saw. Once you have filed it enough times you will instinctively keep it out of the dirt, but yet not have to bend over nearly as much. I run a 2 foot bar on my saw for that reason, and because when you are limbing you can snap limbs off ahead of you a few feet out...it makes a huge difference when you are trying to walk in the stuff.
As for your saw itself Frank, I think you will be very happy with Stihl. I run both Husky and Stihl and my Husky's last a year or two at most...my Stihl's are all over 16 years old and still going. Incredibly robust saws and I beat on them bad!! When the bar gets stuck in a log, I don't cut it out with another saw...nope just yard the log out with a skidder or tractor from around it. Heck in the last 10 years its never seen 2 stroke oil, I just dump in some regular 10w-40 and go for it...don't even measure. The same for the bar and chain oil...flushed hydraulic fluid from the tractors off the farm goes into that compartment.
As for the Easy Start...I have never heard of that before, but it sounds better then the old system they used to put on saws. It was a decompression button, but sticks would often get twisted off and get the decompression button stuck. I have had 2 saws that happened too and so the Easy Start sounds like it works via the recoil and out of the way of regular forestry operations. You'll love your new saw Frank though I'm sure. Definately a great toll to have. Congratulations.
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
