I'm about to test some parts made from prepreg material and I'd like to produce our own prepreg similar to the method in David Algie's now famous video. If I understand correctly, I can obtain a b-stage cure with our existing array of epoxies and vinyl ester resins simply by changing the catalyst??? Can anyone using this method of DIY prepreg production recommend a good epoxy and catalyst to use?  

The Huntsman resins are great, I used them all the time.
