Trilene XT is great... I've used 8lb before without issue. Alot of new guys to the game like using the floating line, I know I did. It's a bit harder to cast and isn't the greatest in the dead of winter, but it really does help you keep the slack out of your line etc...
I'd just spool it up with cheap stuff, get used to the rig then maybe start experimenting.. One thing at a time!
