Do you love big bluegill?
i have a wilderness tarpon 100 ,sit on top and it has lots of room to move around .the nu canoe is a nice looking ride ,.go to you tube and type the one you like and you can watch video about them.
basspro have differant kinds but there prices are fare they have a new ascend fs12t angler sit on top,for around 500.00 .some places have package deals ,with paddle life jacket,,make sure that you get one with a good seat! or you will be sorry, i bought mine from austin canoe and kayak,they have package deals.
That's why I use my Bass boat so I can fish in comfort. Unfortunately for me my back won't tolerate life in a kayak. The body don't flex like it us to. I think I can do a tube though something I may check on next time I go to Bass Pro.
Never fished in either but seems like with a tube you would be able to move your legs around so you wouldn't have to be in the same position all the time. Seems like you would be in more of a setting position.
