Re: Looking forward to Muskie fishing!!
I'm fairly new but my mistakes will probaly save you some money. Most of the serious guys use fairly heavy duty baitcast reels. There are a ton of options and brands you just have to determine your price range. You really want a good size reel like an Abu 6000 series (not saying that is a good reel just a reel ~ that size).
For line, 80 lb test braid is about right. You could go with 100 lb or maybe down to 65 lb and still be fine. Your reel should be capable of holding about the entire spool of braid. The reel line capacity is usually in the diameter of mono so if it says 150 yards of 20 lb test, that will equal 150 yards of 80 lb braid (or whatever the braid package states fir equivalent diameter).
7 to 9 feet heavy action rods are pretty common. I would try to figure out what lures you want to use and then go with a rod that comfortably throws them. Lures are any where from 1 to 11 ounces and it's hard to have one rod do it all. For me, I use a lot of bucktails and they are not super heavy. Some guys use the big rubber baits and they can easily go over ten ounces. Some rods have wide ranges like 1-7 ounces and some are narrow like 1-4 ounces.
If you plan on using a rod and reel you currently own, use whatever you have that is closet to the above and add the braid. I see some guys using heavy spinning combos. There is a recent thread in this forum called Starting a Muskie Box that will give you some ideas on lures.
You will want good leaders. I use 100lb floro leaders but I'm probably going to buy 130lb next time. Wire leaders are a little cheaper. Just make sure they have a very heavy duty snap. I had the snap open on a backlash and watched my $20 lure fly away. That would be a lot worse if it opened on a 50+ fish.
Warning note on this advice! I've been muskie fishing for only 1.5 years and have never caught one.
