Mike- I'm another who doesn't claim to be an expert, but I've learned a few things over the years that might help you. I don't use glue because once its used, any potential mistakes really can't be undone. I also swear by the packing tool; this will keep the hair extremely tight and close, and the fly will float like a cork because water just simply cannot penetrate the interior of the pack.
FWIW, my packing tool is a washer that is large enough to fit over the hook eye of whatever pattern it is that I'm tying. It's very practical because it gives you 360 degree coverage of the hair that's being packed, and if lost can be very easily replaced.
Good luck, and looking forward to seeing your fly in the swap.
