I play the flops like bittydog (more or less, lol). With the Cleveland wedges which have 20, 29 and 38 yd 100% flop ranges, at max range I aim left 3, 4, or 5 grid squares respectively. Back off on the aim offset proportionally at lesser ranges.
Where the flops really help are shorter bunker shots. For BP 15-20 lies dial in the actual yardage, but for CCC 30-40 lies you'll need ~180% of actual ydg (eg, 10 yds to pin, you'll need a 18 yd flop.
As mentioned previously, I don't like the 'aim straight & hit early on the first mark' method because now you have to re-calibrate all your distances. Besides, why break the routine of doing the best you can to hit the ding?
