Well we know that you don't really care much about facts, lab data and science - especially since all the lab data and testing shows spining and floing a shaft is nothing more than great marketing that capitalizes on a mental placebo effect.
Super happy your stumbled upon something that works for you. You speak in absolutes, but then admit you dont have any lab data or physics knowledge to understand the full picture.
And never have I said your putter sucks. All I have said is you need to stop speaking in absolutes. There are numerous factors in how a ball launches
Putter Construction: Static loft, CG height, CG depth, grooves, etc.
Player input: Stroke speed, angle of attack, shaft lean
All of those facto into launch and forward roll. And that doesn't factor in green condition and speed, which could also change what "ideal" launch is.
