Not a lot of people visit the Axe forum, I think.
I've not handled the Estwing Axe, so no help there, but I own a Gerber/Fiskars sport axe, and it's awesome. VERY lightweight, pretty durable, and SHARP. I convexed the bevel of mine, and now it will shave hair, no kidding. The only negative thing I have to say about the Fiskars is that the handle wraps all the way around the head. While this allegedly makes it more durable, on some of the deeper cuts (such as while felling saplings) the forward edge of the plastic handle material can catch and begin to turn up a little from the steel. I just trimmed this off with a knife, problem solved. It hasn't happened again.
Overall, I'd say the Fiskars is a great axe for not a lot of cash. I'll leave it to someone else to help with the Estwing. You might try posting this in the Wilderness Skills forum, those guys use a lot of axes, and I don't think they would mind helping out.
