I believe that the Stihl PM (not PM1) is a very good choise in 3/8" lo-pro.
Whatever brand the chain is, avoid those with safety bumpers on the tie straps.
On the Husky 141, the best cutting attachment probably are .325 narrow kerf, like Oregon 95VP=Husky H30. Oregon, husky and Carton all have bars for this type of chains.
