I've read about using the punch shot w/ full top-spin when you're in the deep stuff* in the forums. But I've heard about using the full shot, too, both using the Cleveland wedge.
On this replay of a full shot (then the punch) you can see me in the light brush 70-80%. I tried a full shot w/ full BS and it went about 3 yards. (maybe my spin should have been different? Suggestions welcome) This was with a starter ball. [note that I was choked at approx 60% power]
So, next I tried a punch shot, the brush was not so deep now (50-60%) but, with top spin it came out at this particular time. Results always vary so use your own experience.
That's what i like about Twitch , I can see may game in retrospect and see the meter & ball spin which isn't afforded on the WGT replays. (the down side is that my 2G is peaking w/ a 100% CPU while streaming, as I never fail to mention)
* 'deep stuff' is generally talking about BRUSH. This is not suggesting '1st or 2nd cut, or just ROUGH', or even 'sand', in this example.
