At the Oct 5th tourney at Skookum, it was pointed out to me that I had a hair line crack in the upper limb of my Z7 near the limb bolt. 3 yrs old with a zillion arrows thru it but never a dry fire nor a bad nock shot. Just one of those things I guess.
I took it to Sportco(closest authorized Mathews dealer)for the warranty work etc.
I also asked if the 70lb limbs could be exchanged at this time for 60lb limbs as my tore up construction worker shoulders aren't getting any younger, LOL.
This was approved and Mathews got Sportco new limbs in short order. Sportco swapped them out immediately upon receipt of them and I just finished fine tuning my "new" bow.
A split nock during final broadhead tuning means I'm ready for late archery elk. Switched from Axis 300's to 340's. Lost a tiny bit of speed but all in all I'm happy with the outcome.
Thanx again to the above companies for handling a warranty issue as smooth as silk.
