Overdraws are thing of the past with the advent of todays modern carbon arrows and high energy bows.
It was nothing more than a quick fixthat made up for a lack of technology at the time for the guys who wanted higher arrow velocity. We all shot them who went through that time period.

Tuning nightmare I agree and a nostalgic reminder of days gone by........so keep it in the garage or donate it to the Smithsonian.
