I have been having mixed results with my Alfa liner fittings I have
experimented with both cushion and locking liners in all three thicknesses.
Some patients/clients have really liked them, but others have given me
feedback that leads me towards a traditional PTB shape. I also have
experimented with a variety of different tension values from 5-12 %. What
type of results are others having? Are there any tricks that anyone has
found?
