The inflatable floats have quite a bit of lift to them. Many people are using these for bluewater hunting. How often do you hunt for 100+ lb fish, anyways? I think the concept you need to go for is what's the lightest in the water (ie. low drag). I'm getting to the point where I'm looking at drag in my floatline and want to decrease that as much as possible, too.
The RA's are great for inshore and such. I've landed a #30 kingfish on a 7 liter one and had no problem at all and I didn't place a kill shot. He ran for about a 1/4 mile or so. Anyways, the inflatable ones are the best if you're traveling. The RA's still weigh quite a bit since they're foam blown. And DEFINITELY stay away from foaming a lifeguard can! It'll weigh as much as the rest of your gear combined.
If you're going to put in the money, and plan to travel, get an OMER or an Aimrite.
Or, if you want to hear a review on the America Float by OMER, wait a bit and I'll report back to this thread when it comes in.
Later,
