Completely agree. I have a range of wedges, and every one is different. I have a Sub 70 that I'm comfortably chipping from 20 feet to 80 yards, and I have a 64 Cleveland that I'm not comfortably hitting for any distance at all but can flop from 30 yards and drop it dead. If I try to work the ball from a distance with the Cleveland, certain death awaits. But from a sand trap? I get out of sand traps more than 9 times out of 10 on the first attempt, and I nearly always cover most of the distance to the pin. And that's with the 64. I wouldn't use ANY other wedge from the trap.
I guess the point is like yours—it all depends on the player and the club.
