i have used a cat 2 for alot of years, and then a cat 6,  i believe,the one with the large butt pack and quiver at the side, but the best set up with a cat quiver i have found is a small daypack with a mini cat fastened to the side of it,opposite your bow arm, it works pefrectly, i normally use plastic zip ties.. but you can have the exact pack you want, even a hydro pack, as well as a cat quiver, best of both worlds..

Thxs for the input guys keep the info coming I appreciate it.. mine should arrive today!!

I had one and I never got used to the fact that it was flat in my way when I tried to sit on a log and glass the country. Better things for me but lot of people like'em.

You can use tha Cat easily if you use a Ribz pack.  The Cat takes some getting used to, but they do work.  

Having access to such, I started one out of alumninum.  No plastic, and only slightly heavier, but it is stout.  It is hanging in the garage, beckoning me to finish it.  Jerry is a great guy and willing to listen to users, hence the large options.

I use either a 2, 3 or 3.5 depending on the situation.  I love them.  You can't beat the convenience.  I use full-length arrows so I can't use the mini because I can't get it long enough.  But otherwise 90 percent of the time I have a Catquiver with me.

I use the C-Q 2 OR 3, pending on my hunting situation, (whether or not I'm on stand all day). I love em both!! For me, it's easy to remove and replace my arrows on the go.
