If you are like me and like having edges for carving in and out of eddies, making tight turns in the thick of things and playing here and there then the Detox is your beast. I would choose the Detox over the Solo as my creek boat because of the edges and the control that it gives me, just remember that the edges also make it a wee bit less forgiving than the rounded hull and sides of the Solo.
The choice is yours, test both and go with what feels best for you.
