There are two factors for using graphite today over glass:
1) Weight. When you come right down to it, glass is heavy. It wears on a person over the course of the day. Even though your are throwing 3oz baits…..that light weight makes a true difference in fatigue.
2) Pretty basic…..Most “good rods” today for muskie fishing are built with graphite. When musky rods are being designed today for a specific appliction (top water, buctails, jerks/gliders), those specific rods are made out of graphite. There aren’t many $20 Ugly sticks designed specifically for throwing jerk-baits.
While you can get away with using the $20 Berkley “Big Game” rod……..When it comes down to finessing the performance of your lure, a good rod is needed……Those good rods are made out of graphite……
You don’t need to spend $200 on a muskie rod. While yes they are nice and light…….It truely isn’t needed…
Gander, Tony Rizo, Cabela’s, Rapala, South Bend, and many other graphite rod manufactures all produce a decent musky rod for as little as $40……Up to $60……
You can purchase a VERY good Gander or Cabela’s muskie rod for $80!!!! Those rods are comparable to the $200 St. Croix or Loomis rods…..
Lastly, get a “good graphite” rod for throwing baits. The feel can make a difference……For you can tell if you fouled up your bucktail or jerkbait due to a small weed. You can feel the grinding of rocks. You can “feel” what the lure is doing under the water!!!
