In my youth I bought whatever arrow the local big box sporting goods store had laying around and some heads I got mail order.
In my 30's I at least started buying the right arrows and semi decent heads.
The last trip around, two years ago, I totally geeked out. Wasted thousands of dollars over the course of the summer trying different brands, different spines. Plus all new jigs and tools and testers. Testing, squaring, knock tuning. Spent months testing all sorts of different fletching, different angles of helical, 3, 4, 6 vane fletching in a multitude of styles and lengths. Crazy minutia like adding weight to my knocks so they'd be the exact weight as the lighted knocks. Played with all different arrow weights that would invariably send me back to square one. 15 to 150grain inserts, 100-300 grain heads. Then buying and trying several brand of
higher end broadheads. Always stupid about it, buying them, then buying a jig to sharpen them, then deciding I didn't like them or wanted to try something else. Heck I probably spent close to a grand alone on that. (this is why I'm poor)
But that's where I ended up though.... "Oh my goodness, this arrow is almost $100! I better bring a junker with me for targets of opportunity." Of course since I had lots of leftovers, that wasn't a problem.
With the new crossbow, I won't have time to do any of that stuff, which is probably a good thing.
Crazy the money I spent/wasted on the bow, especially if I can't shoot it anymore. I went nuts, but I was having fun. The irony being I bought a "cheap" bow BECAUSE I wasn't sure I was going to be able to shoot it. Then I spent ten times as much on everything else. Pissed away piles of money. The arrow experiments, a few different sights, a few different releases. That hit me one day sitting in the tree stand... "This release cost more than any bow I ever owned." (prior to the one I was using)
