Depends on how much play you want.
You could go with a Wavesport BigEZ, Pyranha Inazone 240/242 or I3, or Dagger Outlaw if you want more play. If you want more speed and stability with some play still in there, go for a Wavesport Z or Riot Grind (same boat really). If you want straight-up downriver prowess, go for a Pyranha H3 255 or a Wavesport Diesel 75.
Only the H3 and Diesel are suitable for creeking, though. Since they aren't really the best for any real play and only Hercules can get these boats to squirt on an eddyline, most folks end up with two boats.
If you're interested, I've got a Riot Grind for sale, very cheap, just want to get it out of the basement. It was a hoot on Westwater and caught lotsa waves my playboats never did. Send me a PM if interested.
Join up, suckas.
