The Black Jack Carbon Silica Technology explained.
When we designed the Black Jack Carbon Silica Hybrid fly rod, there were a few design attributes and factors we wanted to include in the design. One in particular was the butt section diameter. We wanted that diameter to not be too big, so that custom builders could use this blank with wood reel seats. In conclusion of design and manufacturing the butt section diameter turned out to be 0.40inches or 10 millimeters, a diameter very easily worked around as a builder.
Aesthetically, we wanted the rod to be unique, not flashy, and somewhat nostalgic. So we went with the clear matte finish and left the blank un-sanded, except for the ferrules which are sanded to insure proper fit.
The action however was something that needed technology in order to achieve what we wanted to achieve. The rod had to be 5 pieces, very durable, not clunky, and seem effortless to cast like a high end bamboo rod might feel, but with a little more tip flex to keep the rod from the typical glass wobble that you get as the line exits the tip section.
The reason that nice bamboo rods are fun to cast is because all you have to do is move the rod in its casting arc and the rod casts itself. This is true because of a few physics principals.
Momentum is actually a combination or product of mass and velocity. A fly rod that is light and thin does not have the natural momentum of a slightly heavier rod like glass or bamboo. You have to push a stiff light rod to flex and cast because it has less mass. We didn’t want this push or fast acceleration need. We wanted the caster to just move their arm and have the rod cast itself, so we knew we needed a little weight in the rod like a bamboo rod, but not much.
Inertia is the principal of an object in motion. A larger mass in motion has more inertia than a lighter mass. So our rod is balanced properly, and has the perfect combination of glass and carbon so that when that rod is in motion it stays in motion until you stop the tip at the end of the stroke. Little effort is needed to cast this rod, yet the tip does not wobble.
If we made this rod completely out of graphite, the rod would have to be very thick in order to gain mass, and when you go thick in graphite, you get stiff. We did not want stiff. We wanted a medium to medium fast action. Medium fast with a 5 weight, and medium with a 6.
If we made the rod out of just glass, the rod would be too slow, too heavy and too big in diameter to be a 5 piece. It also would have a terrible tip wobble. We know this because we made prototypes of this same Black Jack in glass, and it did not work.
So the Black Jack is a Carbon Silica Hybrid. A mixture of glass and graphite. Just enough to give the right weight and feel so that the rod feels like it casts itself when in its zone or sweet spot. This rod is made for floating line, weight forward, and non-weighted flies. Dry flies, small streamers, and light nymph rigs is where this rod works best. And when you do catch a fish on it, the feel is amazing. Better than glass or graphite, and because the rod is a tad bit heavier than normal, more like conventional glass but a tad lighter; when a fish bends the rod and changes the balance point, the angler must counter act to fight the fish and the feel is remarkable even on small fish.
The blanks come with marks on them from JP himself checking for the spline and marking for the guides. You also will get a Black Jack and JP Ross Label, as well as JP Ross Shields and black jack stickers for your rod case.
We hope that you choose to try the Black Jack either for a blank to build, or for a build rod from JP Ross. In our opinion, it is unique and it has pushed us to a new level of technical design for fly fishing.

tip size is 6.0
butt diameter is 0.40"
Blank weight is only 2.2oz, but is tip heavy because of 5 piece.. see info below on levered weight. Use a well balanced reel to counter act tip weight.
Single foot guides and a size 16 strip guide recommended to harness the full potential of the rod.
Some tips for understanding Levered Weight.
A fly rod is a lever, and the fulcrum of the lever is in the grip. Specifically we feel that the exact position of this fulcrum is near the edge of the grip where your thumb goes. So by definition that is the balance point. So when you want to try and find the right size reel to put on your rod to counter balance the tip weight, balance it at this point on the rod.
Guide spacing as follows. Inches form the tip.
