I think I was sufficiently trashed in the other post but for those those that missed it. I cut my 10/11 back 13'. I was happy with it but think 14' would be a touch better. When a good friend got his, I cut it back 14" for him. He seems happy.
If you look for old posts by Speyman, you will see where he posted about the qualities of cutting one back. I believe at the time, he told me how he saw no reason to cut back over 12'. He kept silent the last time this was brought up so either he has changed his mind or didn't want to risk the wrath of the "thou shall not cut a Jetstream" cult :lildevl:
For frame of reference, mine is used primarily on a 1509-3 T&T with 15' Rio or Airflo tips in Type III, VI and VII. Type VIII tips and T14 I throw off of a cutback 11/12 Jetstream on a 1510-5 T&T.
Its only money!
