I'd look around at other manufacturers reel seats as well. Pac-Bay reel seats are on a number of my rods, but there are a bunch of choices out there. I personally think that REC makes some wonderful reel seats that look great. Struble reel seats are also very nice. It seems like the Pac-Bay reel seats are not quite as nice in terms of quality as some of the higher-end reel seats.
For larger rods 8wt and above - I am starting to use Fuji reel seats that you would find on spinning rods. They securely hold the reel and they are very low maintenence - standing up to the salt water very well. They don't look as fancy as the high end reel seats, but the functionality is the same.
There is a site sponser Rod Builders Workshop

Have a good weekend,
