I LIKE this tips ...
If you play above 95 regularly, then best to try a range of the better 2piece balls like AD333, precept EV and the like. This will give the high handicapper an idea how different balls reacts to different conditions on the course. Don't spend more then 50 on a dozen balls
Once scores drop to between 80 to 95, repeat the process but with 3piece balls like e6, nxt, dx3 etc. Don't spend more than 80 a doz.
Once I start playing in the 70s, I'd play prov, b330, Penta or similar.
