7900's x 2 vs. 390XPG vs. 3120XP

Thought I'd run my larger pro saws against one another for a bit of a speed comparison. This particular Casuarina log was relatively even and consistent so no real advantage to any of the saws. However due to sand in the bark the chain by the end was showing minimal, but visible damage to the cutter leading edges. Still have to respect a stock Husky 3120 though, despite being a heavy pig ;) They are a beast...
