@ChiliwackerEC.... I like the versatility of the product and the ease in adjustments for any players physique. Since the foam bumpers are oriented in a horizontal plane, there is no need to try and manipulate the correct angle at address i.e. shaft angle. Also with the speed slot, you have a much better chance of having a consistent path as opposed to a simple foam covered alignment rod stuck in the ground which allows you to swing under plane, but does not prevent you from being excessively low, or "around" the body, getting "stuck behind" e.t.c.
As pointed out by a few, I would like to see the product offered as an attachment only for any tripod, but there is no way of telling from your videos if that is feasible without having to go back to the drawing board. This would help keep the retail price down and possibly increase profit margin. OTOH, the choice to have a heavy duty tripod would help eliminate complaints when people used it on their own "cheap, flimsy" tripods and blame the product rather than their own application of it. I am sure you more than likely considered this and decided to go the "quality" route. In any event, good luck, and hope you enjoy much success with it.

Like some have said, there can be variations depending on the manufacturer. And weight is an important factor in how the shaft performs, regardless of the flex. If you swing an irons and driver with different tempos, that can explain it too. Im much the same. I use an X flex in my driver but Rifle 6.0 in my irons. Ive always assumed their 6.0 equates to a "regular" stiff. A gear head would say i dont swing fast enough to use an X in my driver ( my swing speed is around 105) but I've always loved the way that shaft performs for me.
