Robry, there is no age limit for lessons. Actually, it is a good thing to have a relationship with a coach that continues through your bowling life. You don't have to see one every week or so. But, it is a good idea to have someone who knows your game and is able to critique and correct minor problems when they pop up.
As for the Twisted Fury, A friend of mine has changed over his main balls to the entire Fury line, incl: Fury , Polished, and Twisted. Every one hooks without any problems. All are drilled in lable leverage pattern with pin under the fingers. He finds that they don't snap, but arc, and that's his game. He changes them based on oil conditions and the length he needs. He doesn't bounce, but plays a tighter inside line, and the balls work well at his 215 average. Never checked his flare.
BTW, he is 45 and we see the same coach. I'm a little older. We usually bowl on heavier oil and all of his balls work. He plays more of the middle which is the heavier concentration. His normal line is 20 to 12 and never goes passed it.
