About myself I've not done THAT much paddling, as in insanely high drops,but I reckon I can handle a boat on pretty much anything up to 4 plus without mauling myself...... About the test environment The Findhorn's my favorite river, partly because it's so pretty, but it's also got a great mix of rapids, from flat crap to some grade 5 monsters. Shame the fishermen are taking over (lol) Review The 4twentys one of the most reliable boats I've been in, the reason i got it in this size was so I could use it as a river runner as well as a playboat. As a playboat, it has only two angles- either flat or vertical, so its great if you can cartwheel it, but smaller people seem to find it more challenging. This boat is amazing at getting air. it doesnt even need to be a really big wave or hole, boof and its UP THERE. It also has really nice rails, which makes carving and general surfing great-its also a very friendly boat to roll. Conclusion I can't...
