    So this is just something I’ve noticed and I’m curious if anyone has picked back up in this... why do straight glass rods have so much more backbone then Composite graphite/glass rods?

    To start off my question, there’s a pattern I kinda stick to in terms of how stiff rods are.

    Carbon Fiber > Graphite > Glass.

    Carbon fiber rods are the stiffest, and Can snap pretty easily if energy is focused on one area which is why a Hybrid wrap works well for the rod and makes a just about unbreakable fast action rod. Graphite has a steady parablic bend that is great for wearing down big fish as the rod can really load up with the stiffness graphite provides. Glass Rods are the most parabolic out of the bunch and load up fantastically, and they have a great parabolic bend that distributes energy really well and easily transitions into a powerful backbone, a trait that Harnell has down really well.

    In terms of a composite rod though, shouldn’t it be the best of both worlds for then? The graphite porivides a heavy backbone and the glass allows the rod to load up really well?

    I was recently poking around charkabit when I came across the UC RCE1000 Wahoo (40-60lb) and GUSA1000 Monster (30-60). The RCE being the composite rod, the GUSA being straight glass. First thing I noticed after pulling on the two of them was despite the Wahoo being a heavier rod, it still didn’t have as much meat and backbone as the Monster did, and it loaded up a bit better? Now this puzzles me because Graphite rods are stiffer and taking into experience Calstars Graphighter 900H vs the 90J, it’s a pretty noticeable difference how much more Umph it takes for the 900H to load up and how much heavier it fishes. But this wasn’t the case here at all.

    So why doesn’t Composite rods fish heavier then straight glass? Shouldn’t it make sense the Composite should be a heavier rod because it has the same tip as a glass rod and backbone of a graphite rod? Does it have something to do with the transition from glass to graphite and that rod companies have to make the rod more forgiving to ensure there isn’t a large amount of energy being transferred in one area and snapping the rod?

    Carbon fiber and graphite rods are the same thing just different word play for marketing purposes... GUSA changed the game using aerospace technologies back when they were here in SD under Hastings rod manufacturer. I’m unaware of a full glass GUSA. Their rods are something special.

    Use what works.. haven't bought a conventional rod in a year or ten.. the old rods were literally a work of art...

    I know what works for me... the question is why is it so? I think I’m going to fish glass for my jig sticks and composites for my bait sticks. One thing I have noticed was composite rods have a lighter tip in the lighter rods... I think I’m stuck with that for fly lining.

    No surprise.. the guys chucking iron developed their technique to the rods available, and vice versa in the heyday.. rod load was essentially key for throwing anything more than 100 yards.. surprising.. especially since it still is..

    Tensile strength.

    E glass doesn't take much force to bend. S glass takes a little more. Then you get into the graphites which are much stiffer. The word "modulus" is thrown around when rating graphites. Higher modulus equals higher tensile strength which means more force needed to bend. Carbon fiber is used mostly as an overlay for aesthetic purposes but does add a hair amount of stiffness.

    As far as a rod's action, stiffness, whip, backbone, weight, sensitivity, etc... that is all a combination of materials used, how the flags are cut, taper, wall thickness... etc.

    Consumer demand and price point can be a deciding factor in what materials are used. Also the rod industry is usually chasing what the the reel industry is putting out. Notice conventional reels are packing a greater punch at smaller sizes. A big reason UC is killing it with stronger thinner diameter rods.

    Some food for thought.

    So I just found this out earlier.... the RUSA Rods are actually straight carbon fiber. At least graphite is carbon fiber from what I was told. The difference is how the rod is wrapped.

    Any pics of this RUSA? There are models with the RUS designation. Haven't heard of RUSA unless it's new.

    Carbon Graphite might of been what you heard if it's an RUS model. Just another type of graphite material. Different than the Carbon Fiber I was reffering to which is the the woven material you see in their Platinum line.
