I don't mind using frozen pollen although I prefer fresh like everyone else. Sometimes frozen is the only way to go with the expensive, singe fan purchase that arrived in the spring. Plants purchased south of me bloom earlier than I would like or they only have a single scape that doesn't produce enough blooms for what I need. Anther timing issue is something I want to use that blooms later than the plants I want to put it on. Freezing the pollen allows me to use the pollen the next year before that plant is blooming. When tagging I always write a small "FR" after the pollen name. When lifting tags for no takes, I know if a particular pollen or even pod parent has a problem frozen or fresh.
I use about 30 different pollen parents too. Some registered cv's, many seedlings. Every spring while waiting for the weather to warm I make a breeder book in excel - small image, small box and then a large box to the right - of all plants I intend to use that year. I type plant name or number, foliage and parents in the small box, print the "book" and then fill in the large box with crosses for each plant that I want to make. It's fun to dream while sitting by the woodstove
A look through in the evening before the next days pollinating reminds me of what I planned and also some of those easily forgotten oddball crosses.
Edit - should have said FR is for frozen pollen only.
