After having a bunch more gear stolen last fall, I'm not in the market for a $600 climb saw. But i just got a new 338 for $390. Here's some appx cut times:
Stock 338, stock and new safety chain 14" ~17.5 seconds
Muffler modded 338, Stihl Picco 14" sharpened once 10.5 seconds...... a huge improvement!
200T 16" older chain, sharpened with depth gauges correct 13 s
Muffler modded 192T 14" Stihl picco ~14.5 sec
This illustrates why I'm sold on the light 192T, especially as I have some missing cartilage in my right hand which makes it difficult to work pain free.
I can tell from watching your vid, Reg, that my ported 338 is a fair bit faster than the 540. I've heard it can be muffler modded, but its a job to dismantle the saw to get to the muffler.....
I also saw mweba's before/after woods modding, and that 540 turned into a freakin beast! But I can't see spending 550-600 on a saw and 250 for porting...
