MOTM

I never saw a response to Paul's bonus questions, so I'll take a shot.

#1.  Does 22ga allow for the same drilling size as through hole? Hence 
lower setup costs for production run.

#2.   My guess is DC resistance on coax affecting output impedances.  
Don't have a clue what the length limit would be tho.
