Frank and David   Even though the C.O.R. of each of these heads are the same, because the have different face diamensions the natural frequencies of the faces will be different. C.O.R. is based only on one standard test ball or impacting body. The properly selected ball that matches the face's natural frequency will increase the effective C.O.R. for the club head.   llhack         ----- Original Message ----- From: To: [EMAIL PROTECTED] Sent: 10/12/2004 6:12:20 AM Subject: Re: ShopTalk: long drive In a message dated 10/12/2004 1:41:53 AM Eastern Daylight Time, [EMAIL PROTECTED] writes: driver            1          2          3          4 avg chs       142       148      148       150 avg bs         206       198      198       202 club length   50"        48"       48"       48" spin rate    2100       2100     2200    2400 hd ! wt         200gr      195gr    195gr   200gr launch a     11.5        12        12.5     12.5 hd vol         455cc     444cc   450cc   400cc my smash # 1.45      1.33      1.33      1.34 I don't think that four tests are enough to draw a conclusion. By looking at this chart the only thing that stands out is the difference in volume between #1 and #4. If you could see what #4 did at 50" and #1 did at 48," it might help the process.                                                                             Frank
