I use EFA quivers on all my bows. I like them do to fact that they are light, and hold 4 Simmons with no trouble.
Also use a Cat Quiver 2.5 for stalking at times especially when it is hot and I need to carry extra water plus I can carry some extra arrows.
There are also lots of other quivers to take a look like Safari Tuff's new quiver, the GFA, Thunderhorn, Great Northern, and of course there are many more. I would take a look at what the sponsors offer to see if something catches your eye.
As for broadheads take your pick: Magnus, Zwickey, Stos, Eclipse, Silver Flame, Muzzy Phantoms, Snuffers, Simmons, Wensel Woodsman, and the list goes on an on. Plenty of good broadheads out there and I know I did not even come close to naming them all.
Right now I used 4 blade Muzzy Phantoms, Magnus Stingers, and Simmons land and razor sharks. At times I have all three broadheads in my quiver.
You could even go as far as having different heads and weights for different game.
As far aligning up broadheads if I use 4 blade heads I line when up with my fletching since I shoot 4 fletch. With 2 blades I line when up diagonally with upper part of the head on the right side of the shaft, and the lower part on the left while still being lined up with those two fletching. I gap shoot and this allows me the best field of view. Hope that 2 blade description was not to confusing.
