I have an LL Bean fly rod - they are real nice. Any single action reel would work - no drag needed for grayling - although I'm sure you know that
I would suggest a pflueger model 1492.
Also, if at any time you are dissatisfied, or the rod breaks, you can get a refund or replacement directly from LL Bean. I had a pair of gore-tex gloves that the stiching pulled out(after four years) and LL Bean not only replaced them, but they gave me the difference when the new gloves were less than the original ones.
