Ok from looking at pics and decriptions, I really can't tell what the difference is. What I see is about $10 and the HG has those hook slots. Any differences in materials? Is the U15 better for the extra $10?

I have yet to start my Scott A2 6wt. I am looking for a saltwater seat for it. Another that I am considering is the REC RSLS.

Any other suggestions for a saltwater seat with a small butt?
