Anyone hear any rumors about the mtronic 462? Not sure if I should hold off on the 661c or wait for the 462 or 461c (whatever they are going to call it).

No, was just speculating about the future. The 461 is a very nice saw, just does not have M-Tronic or spring AV, or strato, but that seems to have kept the size & wt in check.

Yeah, but I would sure hate to tangle with it, civilized or not. Certainly good to remember to wear the chaps and not become complacent about safety, just because it is well behaved. One slip up and I'm sure it would bite ya pretty dead, pretty quickly...

So, I messed around with the 7T and 8T rims, about 3/4 tank each. Couldn't really tell much difference between the two at this point.
Help educate me. Here's my thinking, based on the assumption that a bigger rim will provide higher chain speed. I'm looking at it from the perspective of bicycle gears. Chain sprocket is bigger in front, gear sprocket is smaller in the back. Assume that you are running a single chain sprocket, say a 53T with multiple gears in the back, for simplicity sake, lets call it a 3 speed, with a 18T, 14T, and a 12T gear. As the rear gear T count gets smaller, you are actually going to a bigger gear, ie a 53x18 is the lowest gear and the 53x12 is the highest. My bar has an 11 tooth sprocket, with the 8T, wouldn't it be a smaller, lower gear that is easier to turn than the 7T? Am I looking at this wrong?

How so? Does my analogy not translate to saw "gearing"?
No, the bar sprocket is not involved in the leverage, it is just the difference between a 7 pin & 8 pin.
On a bike, the rear sprocket drives the wheel, so it matters. On the saw, the chain does the work, so the bar nose is just like an idler pulley.
And, FYI, the high gear on my bike is 53/11!
Low gear is 39/28. 11 speed cog in the rear ... gives me more range.

My road bike is set up 42/53 with a straight block 7 speed in the rear. 11T also.
The rim sprocket drives the chain on the saw, so this is analogous to the chain sprocket on a bicycle? Bigger rim is like a bigger chain sprocket?

I suppose it translates...if you wanna analyze it to that point thats cool
..8T makes speed at the expense of torque..and verse visa

Therefore the 7T will provide more torque and less speed?
Somethin like that.
Yes, when not in the wood, in the wood the speed may be about the same, and you won't have to be as careful due to the extra torque.

Recommendation then would be to stick with the 7T?
With big bars...yes

Oh, and I handled a 461R in a shop today. It's nice, but just doesn't seem to be the same quality of the 661R. Felt MUCH lighter and smaller, and I realize that the 25" bar makes a big difference when compared to the 32", but PHO, weight difference is only supposed to be what? Like a pound? The 661 is better thought out and constructed, I thought. I definitely will wait until a C-M version comes out. If it never does, well, I've got my 661...

Thanks Ryan. I'm guessing a small bar would be 25" and less? Didn't you just get a 362C? Isn't it AWESOME!?!

Keeping the bicycle analogy for second: Think of your nose sprocket as being more like one of the derailleur sprockets.
It's mainly there to help carry the chain along its journey.
as for the clutch/drive sprocket, try thinking like the rear tires on a truck or a tractor
(2 wheel drive in this example) While keeping everything else the same,
put a smaller set of tires on the drive axle and think of the speed you might travel at.
Now imagine a set of tires about a foot taller.
You'll get more ground speed, but it's gonna bog a lot easier when you start to pull a load.

Makes sense!

Speaking of the AWESOME 362, perhaps I should put the 8T on it, running a 20" bar and 33RS. No? Stick with the 7T?
