Yeah, for big rounds you really need a big saw. 75-78cc is marginal. I use an 066 with a 28" bar and 404 chain to noodle. Way easier than driving wedges.I could have those noodled in 1/4s with my 500i or 372xp in 1 or 2 minutes each. Thats a heck of a lot faster and easier than pounding wedges.
I was gonna get one of those cheap Chinese knock offs of the Husky 288. Then I decided against it as the efficacy of these things seem to be hit or miss.Yeah, for big rounds you really need a big saw. 75-78cc is marginal.
