Tubing choices

[Kota]

We want to buy a two-person tube for our visit to the lake next month. Last year we had a one-person with a well for the kids to sit inside. This year we were considering an O'Brien 2-person screamer (deck type). Anyone have any advice or recommendations concerning brands to buy (or avoid) or deck vs. wells? My kids are 14, 10 and 7. The 7 is a very athletic boy who did fine last year (no fear). Adults will also use it. Thanks.
