Just to make sure I'm understanding: are you saying that the Tornado Terry longer sticks are really balltop Super shafts with an aluminum sleeve?
I believe Terry had his sticks custom made (possibly from IL directly) because they have the same ball top as the reunion sticks. He just had them extended 3/4" and added two E-clip notches and two sleeves so that you can use them in either wood or metal CPs.
Also, by looking at the two pictures you posted, it appears that the Reunion stick is actually a ball topped Competition shaft with an additional e-clip ring at the top (instead of the yellow plastic) and with only the bottom of the 3-grooves
I've not heard/seen this before. Can you confirm?
I think the reunion shaft is something different. The Super and Competition are identical metal shafts, just the plastic top and their distance to the notches is different. Pics below.
What I have found is that if one Top-fire stick is made based on the Super stick, then it will also work in the Super, Competition, and Reunion bases.
If additional E-clip notches are also added with corresponding length sleeves, then you can also adjust how high the handle sits above the panel. Of course you can also adjust your stick higher by routing out material under the panel, OR adjust your stick lower by adding washers between the joystick base and the CP bottom.
