Maybe try something organic. I’ll always recommend the Recess First Base. Specifically though, do you have a price range and any kind of preference? Brand, shape, weight?
And far as bearings I always just use YYF Center Trac. I bought some Something string recently and I really like them, so I would recommend them. But the easy recommendation is Kitty string. Basically, it’s hard to go wrong and even if you get something you don’t like, chances are that someone else will want it. Which is to say, you’ll probably be able to trade or sell it. This probably doesn’t help, but I hope it does
