Just curious if anyone has compared the two arrows. Also what are the advantages and disadvantages of shooting a lighter or heavier arrow?

believe it or not i think the axis if not mistaken are a little heavier than the epics but wind doesnt affect the smaller diameter axis like it will with the epics, i have last years epics and the new supposed ST diameter is not true they are actually the same diameter but a good arrow none the least

Lighter arrows are faster, heavier arrows carry more momentum. Personally, I would go w/ the Axis.

Axis Obsession, I think a slightly heavier arrow is better for hunting personally.

Thanks for your imput, I oredered a dozen Axis arrows this morning.

I been shooting Gold Tips for years and I have no complaint there a great arrow. This year I bought a dozen of the Easton Full Metal Jackets, all I can say is WOW!!!!!!!!!!. The best arrow I ever shot!
