Andrew,
They both work for me, but the Misty Dawn grip does seem to just fall into place. I need more time going back and forth between the two to see if there is any difference in my shooting. So far, I think I'm shooting both equally well.
Between poor weather, and the early darkness in the evening, I haven't shot the Misty Dawn nearly enough! We are gaining about 5 mins. of daylight a day, or about 32 mins. per week, so soon, I'll be shooting till I drop!
Have posted photos of your new bow?
