I, too, have the Eagle three point sling. I like it a lot, especially at around $25. It does an awful lot for $25. I especially like the quick release buckle. It really gets your rifle out of the way should you need to access your pistol in a rush. I like being able to carry the rifle "at the ready" or slung over my back in a more "traditional" type of sling use. THere are several other ways to carry your rifle from the insert that came with the sling (backpack style and some others I can't remember now), but I mainly use the "at the ready" style and "traditional" style, which the Eagle is excellent at both.
With the above being said, I thought I'd try something a little different and bought a Troy one point sling. The quality is fantastic. The pad is an especially nice touch. But (and there's always a but), I find myself wanting to go back to the Eagle sling. With the Troy, the rifle doesn't exactly ride the way I want it to when I'm not holding it. That, and the fact that if you try to move with the rifle hanging (like when you are using your pistol), you WILL get popped in the nuts. That's not any fun, and if it is, you've got bigger problems than which sling to buy. lol.
Long story short, buy the Eagle three point without regrets. You will be satisfied with it's performance, comfort and use.
