Jake, the static spine of your 2117's is just under .400, which translates over to a 75/80. That is static spine though, not dynamic spine. It is not quite as easy as simply matching static spines when converting to an entirely different arrow material. That's why you see Joe Skipp posting he's shooting 2117's and 55/60's out of the same bows.
It is a rare trad set up that truly needs a 75/80 in a wood arrow shaft. I'd suggest you post your set up particulars instead. Be sure to let us know if you're shooting a recurve or longbow, the depth of the shelf (this is HUGE) the bow poundage at your draw, your draw length, and whether or not you are using a high performance FF string, as well as the weight of head you'd like to shoot and how long ideally you would like your arrows to be BOP.
If you do that the crew here can get you close, then I'd suggest a pack of test shafts that is in that ball park so you can learn what the perfect match for you and your set up is.
