Hi so I got fit yesterday and my swing speed sits around 96mph, I had previously hit both and thought the reguar Epic would be the one for me but the Sub zero gave the best numbers by far 10 yards plus. It was also with the Hzrdus T800 5.5 shaft.
I am normally a lowish spin player and can struggle to keep the ball in the air with some drivers so I was surprised the sub Zero won out for me. Amazing what the right shaft head combo does.
I am in the same quandry. Recently I hit the Epic (9 degree, weight in the middle and HZRDUS 55 R-flex) driver on a launch monitor. I have a low 90's swing speed and I tend to miss right. I found out I have a negative angle of attack (-2.5 to +1.0). The spin rate was 2500-3300 with a carry distance of 205-215 yds, depending on how good the strike was. The ball flight was kind of high with not alot of roll out. Pretty disappointing actually, but I know most that was me and not the club. I did not have enough time to test the SZ, but I can't help but wonder if I would have done better with the SZ? (less spin and lower ball flight)
Based on what you wrote, @-AoA, I think the standard Epic is the right one for you. We have found that people with negative attack angles prefer standard and positive attack angles like the feel of SZ better. This makes sense because of where the CG locations are in the two clubs. The reason for your lack of roll is because spin and flight are too high. I would loft it down and probably move to a heavier shaft. That should help all of those issues you are seeing.
Keep up posted!!
Loft is the most direct influencer of spin...less loft is less spin. So for you, we want it at 8* of loft. Taking a 10.5 down to 9.5* would theoretically be worse than the 9* at N,S.
It is kinda counter-intuative. It makes sense that having a positive AoA could require a lower lofted driver and a nuetral one might require more loft. A negative AoA will deloft the club at impact (Right?). So, if I am making contact with a -2.5 AoA and using an 8 degree driver, what would my launch angle look like? How does strike location, with a negative AoA, effect the heigth and spin rate? Sorry for all the questions, but I am trying wrap my brain around all of this.
Angle of attack and driver loft act independently of one another, so one does not correlate to the other. If you are hitting it high with a lot of spin, you need less loft regardless of how you deliver the club.
