I have 2 9' rods (5wt and a 7wt) and a 7'6" 3wt. The 7wt I use mainly in lakes for bass but between the 5wt and the 3wt, I am about 50/50 on how frequently I use them. The 9' is a little easier to high stick and mend especially in some of the "conflicting" curents, but there's just something fun about that little 7'6" rod.
I think it's a combination of personal taste and what you're in the mood for.
My suggestion is to call LRO and order one of each. You might as well bite the bullet now because you know eventually you're going to own them both.
