The tour level balls are the best especially for lower skilled player. Modification can include the pain of losing too many balls ($$$$). The best correction for wayward shots is lessons, but Velocity may stay closer to the fairway.
Without knowing how athletic your wife is, hard to make a suggestion. Companion players may like a TruFeel, more serious women can do best going through the ball selection that you would.

We usually suggest a fitting. But you go to the above icons, and click on BALLS. Read each of the characteristics of each ball and see which would be most beneficial to each of you. What are you looking for in a golf ball? A golf ball is about performance and feel. After reading about the balls, purchase a couple of sleeves and do a comparison on the course and see which you like and which fits your budget. All the balls are quality golf balls.

It does not matter if you are a beginner or novice, man or woman, old or young, the best ball to play is one of the four premium balls as long as you have the budget. Normally a beginning golfer will tend to lose a large volume of balls so the premiums can set you back if you have to buy a box every round of golf. You can also be a beginner and keep the ball in play or have a high income and if so, the premium balls will help maximize your performance. Use the virtual ball fitting tool to see which one suits your needs or get a sleeve of each and try them on the course. If budget is an issue, the Titleist line of value balls are still very good. Whichever you choose, try to stick with that model for a while to help with your consistency.

everyone says use the best ball out there, i have dropped from 17.2 to 11.2 in a year using trufeel that i get second hand. these cost me around 22p a ball instead of £3-4 a ball. now its coming into summer i may swap over to a more premium ball, but i learnt if you are going to shank and cheap ball.. you will still shank the more expensive one

Great that your golf game improvement has not suffered from your ball type. Titleist value balls are still great balls as you well know. For me, I just can't get enough spin on them to keep them on the greens when hitting more than a 9 iron. Too many missed chips so having the highest spinning ball helps me hold a few more greens. I justify the cost by not buying the $8 Starbucks coffee on the way to the course that will just go into the mens room when I make the turn. It's about choices in how we spend our money to get the best bang for the buck.

Find a ball that fits you and your game. Agree with above posts to pick a ball and stick with it.

There is no ball based on skill.. Its what you're fitted into, what feels good to YOU and gives YOU confidence!

With a short amount of time playing, it’s probably not going to matter what ball you’re playing because you’re very much at a learning/growing phase in your golf game. Personal budget plays a huge part. If you can afford the top of the line, go for it. I find the AAAA/AAAAA Pro V1x used balls on eBay are great value (10 dozen for $130 usually). Do the quick online ball fitting and be honest with your answers, and just build from there. As you get better, you can buy better if your budget allows for it. If TopFlights are all you can afford, you do what you gotta do - they got lost all the same in my early years
