We just bought a 3-up HO SeaDoo Spark and I am wondering if this isn't too much tube to use with the Spark. I will likely be towing my kids (210LBS total) with myself (190LBs) on the ski. The one once thing about this tube is that it really sits up on the water as it is inflated under the seats as well. So it goes get on plane quickly, so it may be OK. I have looked for review/comments on towing ability for this ski but haven't really found any.
Also, can anyone recommend a good solo tube for the Spark? We had one a while back but it would bog down and fill with water behind my brother in laws slow-ass boat. While we may use the double from time to time, a single may get more use for us.
