I experimented with a "spring based" PVC "shaker". AI helped me find the spring weights. Some of the fastest fly 10's were holding those. The impulse of power is crazy.

Let's change direction of this acct.
Just a thought... why does Chris Kerr get all of the fun asking questions. Let's jump on some zoom's either individually or a group and either break down some film or ask 3 questions ( I heard that on another podcast).

Will you get mad at me for using the poor man's 1080? (T-Apex) I'll have some video soon. Anxious to see how this can help my horizontal jumpers.
