Not that they can't be, I have built some really expensive ones. You can spend $200 on a blank, $75 on a handle and $75 on guides before you even start on labor, but you don't have to.
I have a client who he and his wife both work average jobs, have 2 kids in school, and have normal financial challenges. They are both passionate about fishing and always wanted custom rods but could not justify spending the money on a hobby. Can they afford custom rods? Absolutely, and here is how.
Just like JC Pennys spring white sale, rod and component manufacturers, from time to time, sell really good stuff for cheap. When they do this I buy lots of it and stockpile it for future builds.
Here is the example
Castaway Intermediate Mod FS 782 blank 6'-6" MH fast in gloss white
Forecast size 16 exposed trigger seat
EVA rear grip and fighting butt
ATC Duralite guides and tip
I would put the performance and balance of this rod up against most at BPS. Add the paint and thread work and you have a truly one of a kind custom that fits in any budget.
The handle with the trigger set at 8.5 inches. He fishes out of a Yak most of the time so he wanted short handles. He is also a Gator fan so it will be decked out in Tangerine and Wild Blueberry.
