This is a bit long, so bare with me.

I recently picked up an arrow scale and am just beginning to get into achieving optimal weights for my arrows. I'm embarrassed to say it, but I never paid any attention to it before. I just picked a shart from the sizing chart and went with it.
Anyway, I read an article by Bill Winke, where he said the optimal weight should be between 6.5 and 7 grains per pound of maximum draw weight. I draw 65 lbs, so that would put me in the 422-455 range.
I weighed my arrows last night and they are 480 grains, about 25 grains over the recommended weight. I also usually put wraps on my hunting arrows, so this will add a bit as well.

a) Is this no big deal?
b) If it is, what is the best remedy?

My first thought is to change arrows. I'm currently shooting a 28 1/4" Easton 2314. The Easton chart also lists 2216 and 2412 as acceptable selections for my draw/weight combo.

My second thought was to use an 85 grain head instead of a 100 grain, but in the same article Winke says that your broadhead should weigh roughly 1/3 as much as the shaft. This is 100 grains for me.

Sorry for the long winded question. Any advice would be greatly appreciated.
