So, I pulled the stock 20 inch safety bar and chain off my Husky 455 Rancher and installed a 16" Oregon Mower Match bar and a full chisle Oregon LPX chain. Should have bought the full skip 16' chisle though. Neverthe less Nevertheless, a big improvment! Makes a good complement to my MS 441. Now, if I could find some one to port and tune it for me I'd have a real fun 'limber'.
