DaHOF i noticed a little distance loss my last couple rounds too. I've just chalked it up to me not compressing the ball enough for full distance and the cold weather.
on another note, local roger dunn had the sim2 demos in. was able to hit the stock clubs, drivers and hybrids. Sound off the sim2 and sim2 max was not as muted as sim, in my opinion. Sounded like getting a nice pop off the driver, albeit in an indoor environment. Now to test with a better fitted shaft to me when they become available.
