I think the power curve on the stihl 4 mix engine would be hard to beat. I run the older 2 stroke stihls also,no other professional models in other brands. The 101 extended feels heavy on the top end but has good reach. Need to keep a good strong hold on it so it doesn't get away from you. I would prefer it when standing on the ground,if in a bucket or climbing I would prefer a shorter lighter model. 101 is pricey, would be a good investment if you use it enough. I bought this summer a poulan pro for my own use.It was under $200 new. Looks built cheap,runs good,I only used it 1 day,it is lighter then the true professional models,has good reach and it easily switches over to other attachments,(string trimmer,blower,etc.) I do not know how well it will last as it is advertised for occasional users.I do think the 8 inch bar is to short and plan on trying a 12 because at an normal angle from the ground up the bar doesnt get deep in the branch of bigger limbs.
