Dennis Swift built a very good Case, Real Leather, Toghht as Nails, had many options, and last it was Heavy. Dennis stops building Case long ago, any one have one IMHO should bother consider parting with it.
I don't think butterfly cases should be allowed in the pool room. Too many people park them on a table for their entire match leaving very little room for maybe a drink or god forbid, something to eat.
Edit: I'll amend that, maybe allow them but require that once you unload your cues you close them and hang them on a chair. Been my experience that no one does.
