I too have a BR600 & use it for power blowing heavy leaves. I prefer the Kombi blower because its fine for most light stuff & I keep all my kombi stuff in my kingcab...easier to store. Blowing off grass clippings, mulch on sidewalks, I prefer the Kombi.
"Pole saw, works ok, the chain tends to "grab" small branches."
Check your sprocket, it might be worn. I've experienced this grabbing quite a bit myself. I have gone thru several sprockets as well.
The saw is fairly new, and it has done that since its was brand new. I has more to do with the chain. I has a troy built attachment plus and that say was a dream it cut stuff like butter, who would think the commerical stuff wouldnt work as good.
