My Light weight Pool Cue Cases in a 3x5 Set-up

My design is based on true experiences over the years of playing and hanging around pool halls observing most of the time whats happening outside the ring of tables and matches. I gathered infos and started taking notes and found out that even our pros carry hard cases(or have a bodyguard to carry it for them mostly their drivers or relatives tagging along) during money matches most of them I still see laying their hard cases on tables on the side rather than keeping them standing up. This lead me to design a case that should be light and flat at the back. So I decided not to put pockets at the back or a pocket in the first place coz it would add up to weight. But on the other hand, since assuming you have stuff to carry like accessories , a pocket would not make any difference since the weight has been scaled up already due to the 3 butts and 5 shafts set up. I have to make another dimension for a 3x5 since this is my first 3x5 project. I am figuring out how to make it still look like an urban gent and as light as possible at 3x5 set up. Weights may vary since leathers have some inconsistency in thickness. But i try to not make it over 1 pound that much as much as possible. so if you carry 20 oz pair of cues its still light. I am trying to make every case as compact and light and as thin as possible even if it is already holding a 2x4 set up.
