what are the benafits of spin vs. bait cast

Skipping flukes/baits, better in windy conditions

Ray I don't know if the US Reels were made for saltwater but I've got 4 of them(oldest about 4 1/2 year old) and have only fished salt water with them and I've had zero issues with them. The only thing I've ever done is rinsed them of with the hose. Heck I've never even lubed them.

Slingin popping corks!

I was skeptical cause the company rep. would not answer my question.
Made me walk...

Sad part about that is their company rep is probably like a lot of companies lately, their reps now what's in their pamphlets and that's it. But trust me they hold up great and are smooth.
