Crazy Numbers

Oh, also I not only get the UD reference, I watched it (old as hell)

Wow! Amazing responses @Ryen and @Gerry_Lager Yes, the balls were 2 piece junk - first swing feedback I knew instantly. You guys made me feel better, I think...lol Actually you did. My real concern was that with this new swing I have gained a full club ++ and thought maybe it was only because of the lower spin rate, not the KFC.

So the 2014 AP1 is a hollow Cavity back iron... That being said.. Typically they do generate less spin then a solid Blade, but not for the reason your probably thinking.. There is a big misconception here. 1st thing I need to ask is what @Gerry_Lager asked, what ball where you using when you got fit.. a lot of fitting companies use crap balls... or cheap hard 2 piece balls and the difference in spin between that and a TP5 or PRO V1 RXS or Zstar are night and day... onto the the misconception... Spin is created by Dynamic loft... so the amount of loft on the club plus the angle of attack from you club is what creates BACKSPIN. here is a picture

Now the reason a 7 Iron AP1 wont generate the Same spin as a Blade is because, Hollow Cavity back Irons have Stronger Lofts then Traditional Players Clubs... So lets say your attack angle is the same,,, degrees in the picture... And we will just use the actual lofts of the clubs for simplistic terms ( I know in an actual swing your club should be a little delofted due to shaft lean... but I just want to keep it simple) your 32 degree 7 iron with 5 degrees of downward attack angle creates 37 degrees of dynamic Loft, HOWEVER, My 7 iron is 36 degrees and at the same 5 degree downward attack angle creates 41 degrees of dynamic loft, thus creating more Spin... So Yes In a way it is your clubs, but that doesn't mean you can't create more spin, you could, @Tom Saguto Pitching and chipping lesson shows that when you narrow your stance you Naturally create a steeper angle of attack, So now your 32 degree 7 iron with a 9 degree downward attack creates the same 41 degrees of dynamic loft and would essentially provide a very similar spin rate, Everything else being equal( grooves are clean, ball isn't wet, ball is open lie and not coming out of the rough which will reduce spin etc). But if you go watch all club reviews from Rich Shiels or TXG experience.. you will notice the 7 irons do spin in the low to mid 5000s because of the stronger loft,(some crazy FORGIVING IRONS has a 7 iron at 26 degrees these days which creates spin in the 4000s) and with the same angle attack as a players blade with a more traditional loft, it has less dynamic loft and produces less spin... THAT BEING SAID... the only way to fix this with new clubs would to find a set of clubs with traditional lofts that is it... Or create a steeper angle of descent as you hit the golf ball. I am sure.. if you did a V1 session with TOM (I KNOW YOU LOVE THAT PLUG) and wanted more spin, so you would need a steeper angle of attack, he could find a compromise somewhere in between your full swing stance and a pitching stance.. (so a little more narrow then your full swing, but wider than your pitching stance that could add a little steeper angle of attack and increase your dynamic loft to add spin... BUT 5000-5500 on a Forgiving stronger lofted Iron is completely normal.. But your clubs are going to roll out a little regardless... so if you had a 150 yards you carry your 7 iron 150, I would just grip down a half inch to an inch.. so it goes 143-145 and roles out. Anyways I am here all year.. .So have NO FEAR..... UNDERDOG IS HERE....(no one will get this reference and make me feel old as shit (sigh))

Thanks for that helpful detail, @Gerry_Lager!

@Ryen is our resident master club fitter and might have a morsel or two to offer.

I would think it depends on what you want the ball to do... lower spin usually means more distance. However, if you want the ball to check up more upon landing then you'd need higher back spin. I'd take the distance. When shooting for the green maybe you just compensate for more roll out? For an 85MPH swing speed I'd say that 5k number isn't too crazy off. Also depends on the loft of the iron. From Ping.com

"As club speed increases, spin rate and landing angle both increase significantly. This fundamentally changes a player’s expectations. A common goal of a 7,000-rpm 7-iron spin rate simply isn’t practical for all but the fastest swing speeds. For slower swing speeds, the average spin rate is actually closer to 5,000 rpm. A golfer has not necessarily been mis-fit if their 7-iron spin rate is 5,000 rpm."
