Buy a cheaper reel and get 2 spools instead of 1 and never debate "floating or intermediate" ever again.
They both their uses. And if you ever get on a boat or kayak you're really going to want a fast sinking line too.
I always carry at least 2 spools. From shore I typically go armed with a floating line and an intermediate, from the boat I usually load up a fast sink on my spare spool as well as my intermediate. Use loop to loop connections for backing and flylines and you can tweak your line selection prior to a trip in about 5 minutes. I've had flylines munched by blues and props on several occasions, with two spools you'll also have some redundency.
