RE: Plano or Doskocil
I am using the least expensive Plano case for one of my bows and have been using it for various bows for the last 2 years. Great little case. Alot of adjustability in terms of where to place the bow straps and the support columns do provide plenty of support for the type of transport that I typically utilize (no plane trips at this point). You can fit some bow stabilizer combinations in there without a problem but others will require that the stabilizer be removed prior to placement in the case. The bow's quiver must be removed though there is usually a decent amount of room for you to place it next to the bow.
Hope this helps.
