Acid wrap, spine up or spine down?

[Ol Pedro]

Considering wrapping my first acid wrap. Spine up or spine down? Clockwise or counter clockwise twist? Also why do one if side torque isn't an issue as it can be in longer battles with heavier fish?Does it cast any better? Does it have any benefits on lighter rods or is it just a fad in lighter versions? I have 2 of the same model blank(30-40lb). I'm tempted to build identical rods with 1 acid and 1 regular dependent on feedback . Or do a matched set, one conventional and one spinning .
