Correct spine has a lot to do with the bow and also idiosyncracies of the archer. I use a weaker spine than most. One common strategy is to get a few full length shafts of the spine you think will work and try different point weights while you slowly cut the shaft down and note the flight with bareshaft or paper tuning. You likely know that a heavier point and longer shaft will weaken an arrow and vice versa. I'll bet you can find a workable length and point weight with that set-up and a 2016. I would caution you not to look at a spine chart or take someone's advice and order a dozen fletched and cut shafts. You could be out some money when the arrows don't fly well. That's why I suggested a few test shafts at first.
Another thing to consider (which would partially negate my previous advice) is how long you have been shooting a recurve. If you are relatively new to it (no idea if you are), then spending much time selecting a shaft and trying to tune it may not be time well spent. I might get jumped on by some for this but I'll explain my reasoning. Before your form has been practiced, it will be difficult to be consistent and get consistent arrow flight. So, when you try to tune the bow/arrow set-up or select the proper arrow, you are in a sense chasing random noise. I notice that if I have not shot for a while, I may think my bow is out of tune, when it is really me that is out of tune and the arrows begin to settle down after some practice. When I started, I got a reasonable arrow spine (which 2016 with a 100 or 125 grain point likely is), set the bow to factory recommended brace height, and nock point height and then just shot for a while. I don't think I got consistent flight out of my arrows for a few months at least, individual mileages vary though.
