I was even that guy myself when i first started taping
I have a Muddy Waters tape I did way back in 81
that wasn't too bad considering the cheap deck with built in mic
but I got to the point that his performance got to me so much
I had to start yelling OH YEAH! and WOO! during Mannish Boy
as far as the Hypers you will cut out a great deal of him
then as you suggested, switch caps and do a comp
the hidden track is nice... but don't put too much blank space on the front
make sure he has to hear it before he turns the disc off
