A 4wt two hander would be pretty intense. I just want to try out the two tip models. They have one tip for presentation, and one for (i guess) high line speed. I suppose the latter would be a bit stiffer?? I'm not sure, but I want to cast one to see if there really is a noticeable difference.

While we are on the subject of gear...What about line? Do you guys usually use something with a sinking tip, full sink, floating??
