Vanes and nock... how many grains?

Ok, I want to play with all of the online speed/ke calculators, and I need to know about how much the plain ol' standard 4" vanes and nock on my Eastons weigh. What should I estimate?

3 4" feathers = 12 grains
1 Easton nock = 12 grains
1 Easton insert = 12 grains
Add maybe 5 grains for glue for insert & feathers

Thanks, Silver. That gives me roughly 250 fps and a KE of 51. Curse my short draw length! :shade:

Yupper...vanes are heavy

I should have noted I weighed feathers, sorry about the confusion.

One of my arrows weighed in at 389 on the shop scale today, which puts EACH vane at roughly 11grains including glue. :mg:
