Chainsaw Repair

I'm still waiting for the 16" Huskie powermatch bar to come in so I can post pics of my 272XP[ I swear they still haul freight by dog sled up here  ]
I have a strong feeling I will put this never used 272XP to work. I will run it with the 16" b/c, 8 pin 3/8 rim sprocket and save about a 1/2 lb by using the aluminum smooth bumper by eliminating the 2 heavy steel dogs [which aren't meant to be used for a heavy duty 16" pulpcutting saw anyways.] The modern 73 LGX sawchain with anti-vibe should help with the 272's rubber mounts over the old style chain it came with.

With this setup the 272 will be my main small timber cleanup and limbing saw. I'll probably just have my 346 for backup. My bulkier 372 with 22" will be my next worksaw in the lineup with the 395- 32" rounding out at the top. My 338XPT and Stihl MS200 are my climbing saws.
Now should I go out and buy a brand new 390XP- 28" to complete my lineup?
