It would be a total experiment Mitch....got a blank you like, but want it with a caster and shorter...can be done.....shorten it up..or add length under the grip..it gets unpredictable when you start getting into the tapered section of the blank. Taper IS everything..A deflection test helps...(Hang a weight off the end and match the curve).But it tells you nothing about recovery rate (How fast the rod unloads back to straight).Fun stuff, but not inexpensive. You will go through 1-2 Ok's, till you get what you want....
