The Siren was a great boat for me at one time. My learning curve really shot up when I got in it. It's so limited though. I hate it on a wave and in a hole and forget about loops! It's great for gettting vertical but it is so pointy it is difficult to maintain it there with any control; it just wants to slice out from under you. I am on the never ending quest for the perfect playboat. I don't want anything too aggressive because I am definately more into river running than playing and I want to be comfortable on big pushy water in it too. I have a squashed Spin I bought from Kat Levitt, and I love it, but it does a number on my back (which has been injured in the past). So... the search continues, and in the meantime, I just want to be able to be comfortable in that damn Siren :) My biggest problem with the sled is that I have to pull it all the way forward and then when I push aggressively with my feet (like when I get vertical) it pushes out and I am loose in the boat! So aggrivating. Anyway... thanks for all your input. Maybe I will give it another shot soon.
