Proforce V2 fitting

[gc0723]

I need your help

Hey everyone. My brother and I are looking to try the proforce V2 shaft? I am looking for advice on fitting.

I currently play a Callaway Ft-3 10.5* w/ a diamana 63-S cut to 43.75 total length. I was looking for something a little lighter that could add swingspeed so I could get more distance, but also remain controlable.

My SS- 94-98 mph
Tempo- medium
ball flight- mid

I would like this driver to be 43.5 inches and from what I have read to play at a firm flex (between stiff and regular I think).


My brother currently plays a Taylormade R5 10.5* fit-on six stiff. He would like a little more distance as well. Also at 43.5 inches.

His SS- 91-95
Tempo- medium
Ball flight- mid-high

From reading about the shaft I was thinking the 5050R for him and a 5050S for me. My questions are as follows:

Will the 5050 balloon on us?
Are these the correct shafts for our swings?
Can the shafts be fitted to a D1 swingweight at 43.5 inches at the correct flexes?
How different will these shafts play than the shafts we are playing now?

Thank you for all of your help. If you are in the Indianapolis area PM me for availability of these shafts. Thanks again and have a great day.
