Man, to think I went to recurves to simplify things. How the heck do I figure out what spine I need without buying 30 different arrows? Learned I can't trust the easton charts to much. Both 2018's, 2114's (at 29" or so) shoot well out of my bow. 2016's at 28" shot well too. A 5575 Gold tip at 28"-29" shot well also. 2315 at 29.5" shot terrible (I knew that was going to happen). 2219's at 31" shot well, but the were flu-flu's, so I toss that out. I guess I need about a 65-70 spine. I want some graphlex or fiberglass shafts as soon as I can find them. Long story, but they seem ideal for me. I guess I kinda anwered my own question.
