Teddy, the shaft does move a bit more toward the sweetspot, which feels great..
I had the new sweetspot on the third ball, and never looked back..

Flattening also should theoretically increase the swingweight. Ever measured before and after Lag? Is it noticeable?

When I put in a new shaft and grip, and add extra epoxy and all that, I am sure it changes lots of things (dead weight, swing weights).. Sometimes I add weight or lead under the sole plate, or in the case of the Hogan, I drilled two holes into the back of the club and poured melted fishing weights into the rear, then epoxied over them to hold them in place.

It's nice to have an organic product you can mess with, manipulate to your liking.

But I have never checked a before and after, because I am changing out shafts, and grips, and trying to get the club to a specific spec.

Steb,

Flattening a club by 3 degrees adds about 1 swingweight.

So you have to go a long way before you notice it.

Cool NRG - I've heard one swingweight point change isn't noticable, but two starts to be, so the 5 - 6 degrees many flatten their irons here by may lead to a noticeable increase.

Steb,

That sounds about right, you probably won't notice 1, probably will notice 2. And it definately does add swingweight, i have checked before and after a bend.

I have a 9 page PDF on Swingweight, i tried uploading it but i couldn't, if anyone wants a copy let me know.. or can advise how to upload?

NRG, if you post a reply, look at the bottom of the writing window after the buttons SAVE PREVIEW SUBMIT, you'll see Options and Upload Attachments. Click on it and a window should open for you to choose where to get the file from and upload it.Very interested in seeing that document. Thanks.
