This just in by email from Mikey. He asked me to post the following here:

I'd like to apologize for the delay returning the flies from this swap. one tier's flies were lost in the mail. because they were in the mail well in advance of the deadline and he's busting his tail to tie up an additional set, I've held off mailing until I receive his flies. in the interim (tonight), I'll tie up a fourth version for y'all as well. it'll be worth the wait. thanks for your patience and again I apologize for any inconvenience.
