It may be worth noting that there is such a thing as a torque wrench for banjo heads. An investment in one might be worthwhile (about $50 USD). This way you can more accurately narrow down just which tensions work best for you and then can easily duplicate it at any time. I feel sure that JanetDavisMusic.com has the torque wrenches available in both 1/4 and 15/16 inch sizes.
