Actually, I was responding to the idea that some deflection is desirable in a cue because it's required for some shots. That's simply not true - you could do anything with a (theoretical) no-deflection cue that you can with a normal cue with deflection, simply by aiming a little differently. Deflection is all negative - nothing good or "necessary" about it - it's just unavoidable with sidespin.Grab two sticks - 1 LD and 1 high deflection/maple. Now take the LD shaft/stick and line up a shot that will produce a lot of deflection in a maple shaft and shoot it. Now, take the high deflection stick and shoot the EXACT shot with the stick in the EXACT position (i.e. aiming at the same spot on the CB and the same spot on the OB) it was in when shooting with the LD stick and you'll miss every time.
Now translate that into the shot you're thinking, soft masse around a ball. Given the parameters above, if you shoot it one way with an LD it would have to be shot a different way with a HD shaft. That's Patrick's thinking and I agree; however, I don't believe shooting soft with both an LD and HD shaft are much different so in YOUR particular scenario I don't believe you would need to move the cue to adjust between LD and HD. If you were shooting that masse shot hard then yes, the stroke and angle of attack would be different for LD and HD.
