It is much easier to tune an arrow to your bow, when you are not trying to tune the set up for a specific broadhead weight. There are plenty of options in all manner of weights and configurations to match your dynamic spine requirements.
Both of your arrow choices are good ones, but maybe also consider Beaman center shots, and Gold Tip trads if you want to stay with a wood grain finish. They are both also great arrows for a cheaper price, and the GT's you can often find 'blems' on sale for a really good price.
If you have your own saw and plan on cutting your own arrows as you tune, invest in some Ferrel-Tite cool flex, hot melt. It's made for use with carbon arrows, and works really well, especially when removing, trimming the shaft, then reinserting the inserts. The axis shafts, with their hit inserts are a bit more difficult and time consuming to do this with.
I don't like to hunt with anything less than 500 grains. The more the better in my opinion. More arrow weight will yield more down range KE/momentum, quiets the bow more, and provides less hand shock. Too heavy though, and trajectory suffers. I personally like 11-12 gpp.
