RE: Which would you use?
Those are some excelent shafts. Super tough and tolerances are great. Much better than the axis shafts. I used them last year with excelent results and will very likley use them again this year. The CX400's I decided to try this year may be just a little too light for my tastes. A little too much noise at the shot.
No question about it. I would go with the Terminator selects.
You will never notice the 5 fps difference in the two shafts.
