Longbow hunting arrows, questions

[jeprli]

I'm new to longbow archery and would like some opinions.

60' longbow, 45lb@28", 28" is my limit.

Currently shooting 400 spine carbon arrows with 125g tips, total arrow weight is 400 grains, 29" long. They fly straight and i'm happy with that. Trajectory seems ok up to 20-25 yards which i consider my limit for now. Would this be a good choice for whitetail/mule deer? Or should i go for lighter/heavier option?

Any specific broadheads/arrow weights you guys tend to favor for this weight package?

Thanks
