I'm looking to upgrade from my my stock Excalibur "S" shafts to something a bit more ergonomic. My plan now is to eliminate the entire aluminum upper and run a one piece carbon fiber rod the full length from the coil to the control housing. Has anyone here made any custom shafts for diving? I'm especially interested in seeing those for the Excal, but pictures of other models may give me ideas as well. Thanks in advance. John.
