Scott,
I'd have recommended you go for 20/30/20 tension as you reference,
because the wing structure only has to give an extremely small amount to
give up tension. 6061 is
somewhat like bubble gum and a rib with channel reinforcement will
deflect and with additional tightening repeated, you will see more loose
cable. I don't think for a minute
that lack of tension could cause problems, but certainly over tightening
will eventually cause you grief. Look carefully at the skin where the
bellcrank is located and see if you find any indication of reading the
flange line. I've seen the rib pronounced at this location where cables
have been over tightened and for that reason I maintain the lesser
tensions without problems. Different wing on my HDS of course, but I
have the same concerns.
