I've been thinking of going to Home Depot and getting a long piece of that white plastic (PVC) lawn sprinkler type pipe, about 1" OD, 8 feet long, and just drill a hole in one end, to pin it to my cross bar.
Light, flexible, and about 1/30th the cost of a $300 carbon fiber battle stick.
On all my previous cats I had a slide-adjustable stick, but on my Blade it's a fixed length. At first I thought it was a PITA when tacking and gybing, but now I'm used to it and I actually prefer it.
I never have to worry about it slipping in or out when I'm doing my thing.
