I'm sure you can do what you want to do, but it's a little tough to steer you in any particular direction without knowing more about what you shoot, weight, draw length, etc.
For years, I bought the Gold Tip arrows made by Black Widow. I'm sure that either the Gold Tip 3555 or Gold Tip 5575 would work for you, as long as you're not drawing less than 35# or more than 75#.
If you're drawing between 50-55#, you could either go with a 3555 and a lighter weight tip as a target arrow, or a 5575 and a heavier tip as a hunting arrow, assuming your draw length is somewhere close to 28". On either side of the 50-55# range, the choice is rather obvious. If your arrow length is much more than 29", then you'd go to the 5575 at a lower weight range, and if your arrow length is much less than 28", then you'd stay with a 3555 up to or maybe even past 55#.
Once you decide on a basic spine, and cut the arrow 1" past your draw length, you can "fine tune" it, so to speak, by trying different weight points, 100 125 145, until you see what flys best.
None of this is as good as bare shaft tuning, but it will get you close enough to have an arrow that flies well enough that it would be hard to tell the difference.
Just noticed you're from Mid-Missouri, so you're probably not that far from Nixa. I'll bet if you went down there, the boys would help you get set up with an arrow that would work for you.
