What size pitch lap would you suggest for a 14.7" F/4.5?
I plan on using either Burgandy pitch or a 50/50 mix of gugloz 55 and 64.
I'm working at about 70 degrees F which would you prefer?
And finally, should I make more than one lap? One for polishing and another
for zonal figuring?

Thanks for any suggestions!
