Sling are a serious matter of:
A. Preference and
B. How you plan to use the rifle.
If you are going on long humps off into the hills and don't expect your game to come jumping out at you, there is always the simple and effective 2 point sling where you can throw it over your shoulder and hump all day.
Then of course there is the single point sling with the 2 point sling conversion clips that can be converted back and forth with a couple of quick changes of clip placement.
Then there is the strict single point sling (which I use but I actually have more than a dozen hanging around of all kinds).
Then there is a 3 point sling as well and wow, it really just goes on and on.
I think you should first evaluate what you will normally be using this rifle for and then figure out what MIGHT be the best sling to fit your uses and then take it from there. The good thing about my single point is when I'm at the range, I just pop it off and leave it in the case so it works for me.
And yes, I know, I didn't REALLY answer your question
but like I said, it's strictly a preference thing based on purpose minded discovery.
Check out the "slings" tab and see how many options are listed there and then start thinking about it. The good things is, most slings are pretty cheap so if it turns out you don't like your first choice, nothing wrong with having spares around...
