That diet would be wonderful for your gliders. Gliders on Priscilla's diet live long, healthy lives. It is one of the diets I feel comfortable recommending to others.
Yes, you make the diet and freeze it. There are a lot of people on TSS that feed it. PM me if you have specific questions. I do not feed this diet, but I would be more than happy to put you in touch with several people who do.
