I'll guess your arrow length to be 29 inches. Please correct me if I'm wrong.

Shaft 290g
insert 15g
nock 12g
Vanes 24g
head 100g

Total arrow weight 441g. You look fine as far as weight.

If the 250 and the 4560 are infact the same shaft you appear to be underspined though and that could make tunning difficult.
