I can fit 5 in both of mine no problem, but I really have no desire to walk around like Ted Nugent with a full aresonal of arrows in the quiver when 1, maybe 2 tops is all that is needed. That is why I take 3 Broadheads placed on the outside of the quiver, and 1-2 judo heads or blunts on the inside slots for plinking/stumping on the way to the stand, or for small game.
Not to mention, I just don't like pulling the broadheads from the inner slots of the quiver. I'm always afraid that I'm going to either nick my hand pulling from the inner slot, or cut the string or worse yet, both of those. So that is why I don't like carrying more than 3 BH's with me, even though the quiver is more than capable of doing so.
