I've read up online about them and everything looks great. Low noise and very powerful 235mph at the end of pipe,64db, 20.5lbs. I can't seem to find any reviews on lawnsite doing a search so I figured post a new thread. I'm considering a Stihl br600, Shindy 802, Kawasaki krb750, and now a Solo 472. Any thought? Thanks in advance guys!
