Our new Aero-Shaft is out! We designed this for those folks that didn't want to put our Aero-Swings on their own drivers. Aero-Shaft comes in 5 sizes; 30"(indoor training), 39" (iron length), 44" (Driver Length), 48" (Long Drive Length), 48" Whip Aero-Shaft (Tempo and swing speed trainer). I'll be at the World Amateur in Myrtle Beach the end of August with a booth set up, and we are at the PGA Merchandise show in January. Let me know if I can send you a sample, and if you get to either of these events, please pay me a visit! Bill - Aero-Swing president
