Par4QC Apparently you didn't. Momentum equals mass times the square of the velocity.

Ynotgolf I ditched mine and bought a bunch and here is what my results were.
Winner Loser
Ping G410 plus. Ping g400 max
Pxg gen 5. Ping g400 max
Ping g400 max. Pxg 0211
Sim 2 max beat them all.
Pxg 0211 straight shooter similar to the max but gets beaten on distance. The right shaft in a g400 max could possibly be top dog or just get lucky. Counter balanced shafts make that heavy head feel comfortable. When I switched out to a tour 65 it felt super heavy to me. The stock Alta in my g410 feels much more stable than the stock Alta I had in the max.

Makes sense. I had same success today with it. Club feels a little heavy, but I'm getting"through" the ball with it.

I put the Alta CB R flex PING shaft back in the G400 SFT head for today's round. Other than feel, I cannot tell a difference in performance.

    azgreg I'm putting them in a TM R580 driver, TM V-Steel 5w, and a Nickent 3DX 4h.

    Please share your reviews. You going to have to shim the TM driver and 5W? I think those are .350

      sdandrea1 No clue, no guess.

      2 things I've found in using them....
      Driver shafts- color makes a diff..... yes, believe it or not. White or Neon are the best 2. The best was the black/silver which they no longer carry, for some strange reason. I say this about the colors even though the stated weights are very accurate in the 67-68g. range; never had any outside that. Maybe a rare 69g. 1 time.

      Iron shafts did not perform (for me) as I wanted. Seem to be too stiff (tip) per flex, even at A. Never dropped to L, so no clue how that plays.

      Great shafts though, after all these years, and still basically the same $10. Gotta like the weight though, to want them.😉

        I put a white FGS that I got from Par4QC into an Adams 9088UL driver head I got from sdandrea1 and it’s a great combo. Those FGS driver shafts are an incredible bargain. Very stable.
