Ididnt care for the TDR reed back in the 90's, After few Glamis trips I would inspect the reeds and they would after a few trip be lifted and not sealing, said the hell with them and went back to OEM and never had a problem, then up graded to the VF-2.
May want to get a hold of Jayson there are some carbon fiber reeds that RK used to use that worked really well I was told. I cant remember the MFG.......getting older aint for sissys
