Ironically, i modified it with a wood + juma combination and couldnt be happier. got it playing to where i like it, plus the feedback of the shot is firm now & not mushy. I'm sure micarta or IV3/4 works just as well.
did you follow the same dimensions for the original ferrule for the micarta upgrade? I did that with juma and the deflection was higher than the original.
It is at 0.855", normal cues are around 0.843'
Funny you say Ironically because no I do that same kind of weight saving " hack" with a hybrid Vplat with it being hallow in the stem in the shaft and filling the void at the top with a wood plug. Plus Micarta is second lightest only to tomahawk and then wood of course. My whole Vplate is only half inch in total size! Also ironically my Juma setups I do the same with wood and have done that to my Revos, cynergys, and Bcue shafts in the past with lots of success on making the hit better and making the deflection lower or the same!
I'm glad you have had success with the Juma setup!
