I measured the FOC and its about 19% which seems pretty high. The total arrow length, including the point, is 30 3/8" and the FOC is 2 7/8".

The shaft is 29 3/16" long at 6.9gn per inch and has 3 x 1.75" FFP vanes weighing 9gn total. The nocks weigh 2gn but I don't know how much the pin adapters weigh. Can anyone hazard a guesstimate as to how much the points weigh? I reckon they would be around 100gn but I'm not sure.

PS. I have tried contacting the guy I bought them from but he hasn't replied and he doesn't seem to be the type of guy that'll know anyway..

Thanks
