Hogwired:
I have another question -- Does a 282yd driver make considerably more than a 4yd improvement over my 278yd driver?
Since no one addressed this question, I'll take a stab at it. Yes, using the level 83 Callaway xhot driver which I currently use as an example, it averages about 300 yd/drive for me. It has a high trajectory as opposed to the med/high trajectory your current driver has. The high trajectory is useful for driving over trees, cutting doglegs and it lands a little bit softer. I found that the lower trajectory drivers would fall short if I tried to drive uphill in some situations and they were harder to stop on drive-able greens. The extra yards, high trajectory and the slight increase in precision the Xhot, SLDR and other drivers in that range have does make a noticeable difference IMHO.
As far as the hybrid/3 wedges debate goes, I stand with the others on the 3 wedge side.
