I tried a couple of Raven shafts. One wasn't bad, the other I didn't care for, and I had one custom made, and I didn't care for the blank. I hit with a Cynergy, which was ok, but in the end I kept coming back to the AVID.
🤷
I believe that Balance Rite might make an extension that would accommodate some of your cues. It might be easier to get an extension between the joint pin and the shaft for the rest.
Hope this helps.
