Ahhh, the musky. My favorite fish to chase...and be frustrated by.
Personally, I have a St. Croix 6'6" Musky Rod. Works great for musky cranks, jerk baits, and heavy bucktails (1.5 oz or larger). I have it paired with a Tica Caiman 200 reel. If I were to do it over I'd probably go with the 6' 10" version though.
The current movement in musky fishing is to go longer with rods. There are many companies that are now making 8' and 9' musky rods. I imagine they would throw these large baits about a mile. That's all well and good I suppose but I've always wondered how you transport them. (I don't have a boat)
However, I recently read an article on In-Fisherman called "Musky Lite". It was interesting because I have been thinking that bigger/heavier isn't always the answer. I've noticed that I've had more issues staying hooked up with musky using my musky specific rod then I did using my 6'6" bass casting rod when casting my favorite small bucktails. Also my most productive musky lure is a 3/4 oz. Mepps musky killer that has about 1/2 the hair ripped off if it. This is a lure that is manageable on a MH/H action bass rod. As an aside, my brother has no issue hooking up and landing them on his walleye rod with an Erie Dearie. :
So, with this in mind, a couple weeks back I picked up a Kistler 7'8" Magnesium Flipping stick as a closeout at Cabelas. I bought it to serve duty as both a bass jig/light swimbait/frog rod and light musky bucktail rod. I've not thrown a bucktail with it thus far but from messing around and throwing baits that are similar it seems like it will do the job fine.
So long story short(er). St. Croix makes some excellent and reasonably priced rods. However, if you are just throwing spinners/bucktails then a heavy action bass rod will serve the purpose too.
