I put this on the Bowhunting section but no one answered,so maybe some of you guys that bow hunt elk can help me out.

I'm getting back in to bow hunting,I have not been up on it in a few years.I had a PSE Nova that I hunted with for a few years then time always gets short when bow season arives,so I sold it last year.I have a 30 inch draw and I can shoot 70 lbs easy(Last one was set at 72 lb)
My question comes as this,the bow will be used for elk hunting,I'm a experienced elk hunter been hunting these critters for almost 20 years with a rifle.
I was looking at these three bows wich are the best.
1.PSE Thuberbolt 60-70#
2.Reflex Grizzly 60-70#
3.PSE Fire Flight 33 60-70 #
Also what do most of you elkhunter use for arrow Carbon vs Aluminum.I used to shoot easton xx75 game getters II,with bear broadheads 125 gr.
I was thinking of a Carbon shaft arrow and Magnus Rothar Broad heads.
I was looking at using a Trophy ridge 5 pin sight(10,20,30,40,45)
NAP Quick tune rest,and Trophy ridge stabalizer and SLV vibration reducers.
Any suggetions on set-up,or equipment.
Thanks BBJ
