Our games are very similar. Drives pretty much the same, my 7I is 155. Make more greens than miss but miss my fair share. I'm a 10 hcp since financial constraints have cut me to 1 or 2 rounds a month and I don't practice.
Fortunately a local Nevada Bob's store allows me to put together my own mixed dozens, charging only 1/4 the dozen price for each sleeve when purchased in dozens. It gives a great opportunity to try the different balls without having to put out a bunch of money.
Over the last few years I've gravitated to the regulars instead of the "x" versions of balls for the extra spin. You will give up maybe only 2-3% distance-wise but you'll really reap the benefits on stopping power, chipping and putting.
This year I switched to the Srixon Z-Star simply because as I get older my eyesight gets worse and the neon yellow cover is much easier to spot in the air and in the rough. It's a great ball and the one to use if visibility is an issue.
The premium balls are all so close now that it's a matter of personal
preference and what fits YOUR game and eye.You should definitely try
various balls.
