I'll give you the distance arguement if you are dealing with trajectory/spinrate issues from your angles of attack and headwind / downwind conditions. But from pure ball speed perspective; 5 yrds difference - tops. People forget, the C.O.R. of the modern drivers make the compression differences of balls less of an issue. Example; I tested the highest compression for 2012 Cally Hex Black Tour (117) against the Wilson DUO at 51 compression. The ball speed difference over 10 well-struck drives each was .72 MPH of ball speed. My swing speed avg is 108. With all the marketing hype around ball compression to fit swing speed - you'd think I had just broken the laws of physics. Took the balls to the course and bingo!.......... no observable difference in distance of the tee.
I'm no physicist but I do know that ballspeed isn't the only factor in hitting it long. You yourself mention angle of attack, trajectory and spin rate.
What I DO know is that on a course I play between 30 and 60 times a year I hit the RX to 122 from a green that I've NEVER been closer than 140. And the wind for the 140 was quite a bit more (behind me of course) than the day I hit it to 122. Just about ALL the other balls I've tried - best is around that same 140 yardage
In fact, a young buck who generates around 110 MPH (I average around 99-100), a couple of times that day told me "Catch that" and not only did I catch it but I went past it. At one point he asked me if I was on steroids.
I've backed off of the RX to the RXS because the RX released too much on the greens, about 15 feet or so on average, where my old TM Red LDP used to be consistently right alongside its pitch mark. The RXS is not as long as the RX but it does stop better, maybe an average of 8 feet or so past its pitch mark. Still looking for a distance ball that stops like my TM Red.
So while I can't claim LM numbers and I haven't played every ball out there by a long stretch, what I can claim is the RX is the longest ball *I* have ever hit, and by a fairly large margin.
