Core bond...pre-made retail or mix your own?

As the thread title suggests,
What are your thoughts on core bond putty...retail premix stuff like ATC Core-Bond, or just mixing your own putty?
ATC Core-Bond up here in Canada is pricey....$210 for a 5 gallon pail....but I think spending the extra cash for it would be worth it due to it always being consistent, and in my Viper rebuild, I have rough estimated that I'll be bonding approximately 50 square feet of balsa core, and just over 4.6 sq feet for the transom.
Trying to remember what ratios of cabosil (fumed silica) and fibers mixed in with resin to the consistency you like in your first batch might be problematic to duplicate in your subsequent batches.
If mixing your own putty, what ratios of cabosil and milled fibers works best?
Does resin type affect this? ie regular polyester versus vinylester?
