Another vote for Compre rods and Shimano reels here. I have a couple of the Pete Maina combos and they have never given me trouble. The drags are good and they cast very well. The only negative side to the Maina combo that I could find was that the clicker is not very loud. Did you hear that Pete? It's still something very minor.
As far as tethering your equipment is concerned...DO IT. This year I put a SS cable to my bolt cutters and long nosed pliers. They're very easy to drop and forgetting about the expense, dropping your cutters in the water means cutting a trip short cause I can't see how you can continue muskie fishing without them.
Good luck.
