I don't shrink condenser tissue. It keeps on 'a-shinking. I live in an area of radical humidity variation, too. Some people (from Sears catalog days in the out-house) ruffle their tissue. Works fine.

I weighed a few 110 and 120 sqr/in pieces and found that the post shrinkage weight was now 0.00695 grams/sqr/in or 15.8% heavier than before shrinking (0.006/grams/sqr/in).This can make a difference to an A-6 with a 50 % stab area of 0.04275 grams (45 sqr/in total flat area only) and a bit more if dihedral or tiplets are added in.
