With the exception of Jump shots, there are no shots that, I have ever seen, that can't be made with low cue ball deflection shafts. LD shafts don't jump as well, but that's it. Tate mentioned masse shots, but all you really have to do is aim to miss the interfering ball. With HD shafts, the squirt pushes the cue ball to miss the interfering ball, but with LD, you have to aim more to the side to miss it. This is nothing different than a cut shot where the ball goes where you aim instead of squirting to the side.
One thing I would like to point out is that all players, for as long as we have been playing pool, have been making adjustments to their aim for changes in deflection or squirt. Remember how, when you got that new cue 15 years ago, you had to play with it for a few weeks to really get used to it. Very often, you played really bad and couldn't make a ball for a while. The difference was, most likely, caused by a change in deflection or squirt. Not all HD shafts squirt the same so when you change you would miss balls. After you played with it for while, you would adjust.
Also, as your old 13mm shaft gradually became smaller from the reconditioning and tip replacements, it gradually deflected the cue ball less and less. You adjusted to that real easy because it was very gradual, but when you got that new shaft, back at 13mm and this time with an ivory ferrule, all of a sudden you couldn't make a ball!
Welcome to the realization of changes in deflection or squirt!
LD shafts have become popular because they allow new players to learn to adjust to squirt much more easily, but they also allow the great players a better margin for error. When that great player misses his aim by just a little, the difference is much less so, he will make more "slightly miss aimed" balls than with regular squirt or high deflection shafts.
There is no doubt that switching to a LD shaft takes adjustment, but so does most any cue or shaft change. It's a bigger change from HD to LD or vice versa no doubt, but it really is the same thing.
