I'm looking to buy my second float tube. I have an ODC 420 right now which is great, but I've decided I want something more lightwieght and that packs down smaller. (The ODC is 16 lbs and the foam seats restrict packing.) I've narrowed it down to two tubes, and was wondering which one you guys, from experience, think would be better:

the new '06 model High Adventure from Buck's Bags

or the Caddis Navigator IV (or the Nav. II is you name know an important difference betweem the two.)

I know both of these brands are used by a lot of you guys. Anyhow, any help you can give is awesome, and much appreciated. Thanks.
