When I got my first 044 back 9-10 yrs ago, then my second Madsen's tuned one, I thought they were the best saw ever, lots of power, light weight; a great saw for use in a tree. But when I got my first 372 20 months ago, also Madsen's tuned, I forgot all about the 044's!! Even lighter, smoother, more rpm, a bit more power, and a filter that stays much cleaner... Now my Walkerized one really screams...and I guarantee my next one will be dunn by Yoda (Mr Ken Dunn)---or the Greff man, who has done four others for me.
Next project is doing the other 372 muffler, then I can really compare Madsen's work to Walker's...
I cant believe my Greffardized 346. i only have a 16" bar on it, so it really screams. i removed a hemlock today, and after sending down the Walkerized 335, I just kept blocking with it, cutting doubles, all the way down to about 20 " size, usually a pain, as the bar wont go all the way through. But that little saw is so darn fast, and light, it is a joy to use. Specially as it was nearing the end of a 9 hour day, after a 11 hr, 90 degree one yesterday, so my poor ole bod was starting to cramp up.
