Practicing about an hour a day, it took me a week to get a good feel.The first hour or two is mostly break in. If you don't like it after 10 hours or so(give or take), try something else. And dont be led to think brand A or brand B (or whatever brand it is) will not need a break in period. They ALL need it. An hour or two break in AT THE LEAST to really see how a tip is going to perform.
The better your stroke, the quicker this process will be. But don't judge a tip too harshly by just one or two hours of play. I've heard some here on AZ that condemn a tip after a few games. Then they state they cut it off and went with what they are used to. Mostly because of bias. They were not willing to learn the nuances of a different piece of equipment before giving up. When I started using my (now favorite) tip, I had a bit of a rough time. I stuck with it and am no longer looking back. Not saying I wouldn't try something else if I had a reason, but am very happy.
