The Aldila MOI Proto shaft is designed to maximize the performance of the new high MOI heads. Combining nano technology and a novel design approach called Nano Enhanced Tip Technology (NET2), we are able to achieve the increased aMOI (area moment of inertia) required to offset the unique bending and twisting loads high MOI heads have on shaft. The improvement in the aMOI of the lower section of the new MOI Proto is done in a manner that also substantially improves the cross sectional stiffne
