You can't go wrong with The Tetons. I have been selling them in my shop for three years and have had no returns. I fish them in the salt all the time and they show no signs of corrosion, and I am bad about always rinsing them.
The multi tip lines have some plus and minuses. With the loop connections you will always get some hinging, but for about 100 bucks you get three lines and dont have to purchase extra spools. I have sold a few Rio versi-tips and people seem happy with them.
REI will get you a good price, but they are hurting small flyshops, who provide alot more than just merchandise.
