Ifference between pro series oval link chain and regular oval link chain?

I'm looking to buy my first fire set of poi and would like to know what the difference is between the pro series oval link and regular

If you are talking about the chain with attached handles, on one set (Pro) the swivel is connected directly to the handles via a welded ring, on the reguarl, there is a quicklink I beleive.

Thats pretty well it. I think that MAYBE the pro series is thinner also, but thats easily checked on the specs on this site.

Thanks not sure about the thickness but after studying the blown up pictures i noticed that the handles are welded directly to the chain. Thanks

CORRECT, the pro series chains all come as one piece, with handle, that you can then attach a quick link and poi head to, most of the other chains have quick links at both ends. The pro series also have welded on swivels at both ends.
