I've had better luck with the 3-9x38 than the 2-10x38. The eye box at 2 power is not good in my opinion on the 2-10 and what good is 2 power if isn't quick and easy to find your way through.
I'm a Weaver believer and own at least a dozen Grand Slams, classics, and classic extremes but I steer away from the classic 2-10. The classic 3-9 or 2-7 are better bets and the grand slam 3-10x40 is great.
