heavier arrow with lighter broadhead

[sagedoc]

Which is better and why. 280gr arrow with 125gr broadhead or a 305gr arrow with a 100gr broadhead. Is there much difference in performance or does it just open up more options for broadheads since there are more 100gr broadheads out there? Total arrow weight is the same.

Thanks

Add the weight to the insert, it opens up the options for you to use 100 grain heads or heavier.

So any flight/performance differences between a 300 grain arrow with a 150gr broadhead versus a 350gr arrow with a 100gr broadhead? Is there a big difference?
Thanks
