Yeah I don't think 11x TeeBirds come any cheaper than Brinster TeeBirds and I've got a couple backup Brinsters already so I think I'll keep those in the OS slot. I'm sure if I lost all of them I could find production run max weight JL TeeBirds just as OS for a reasonable price. I could use a Valk or Mamba in the US slot, but those are wider-rimmed discs and I'd rather keep my fairways in the speed 6-8 range for more control and fairway type distance.
Are you looking for something cheaper for the in-between slot for yourself or for me? AJ TeeBirds are slightly more expensive b/c you have to buy off the Factory Store, but I have a couple max weight, production Star TeeBirds that fly very similar to my AJ now (not as OS as the AJ was when it was new but stable enough to fill its current role). The EchoStar TeeBird is very straight for me and also not very expensive to replace (mine is actually a factory second so even cheaper to replace).
I think my lineup is honestly not that hard to replace except the PFN 150 TeeBird/PFN 164 TL in the US slot. Of course I could just take a chance on a production run lighter TeeBird/TL in that slot if I lose both of them, which is probably what I will do eventually.
