John, I asked this over in the cue case forum, but you have not been over there recently.
Have two questions.
1) What is the difference between 1st generation and 2nd generation Rugged cases?
Mainly the way the strap is done. The strap is now done with a fixed pad instead of one that slides along the strap. Unless it's a leather shoulder pad then we do it the slide method.
Also the second generation all comes with a nylon ring spliced into the interior at the lip to insure that the interior never develops tears from the fabric rubbing the edge of the plastic tubing. I tested the tear strength of this by sewing two handles on a piece of nylon and putting all my fat ass weight on a piece of metal tubing with sharp edges and pulling to try and see what it could take. So far we haven't had a single failure in this area since I started making them this way.
That's about it. Of course we are always improving and so there are other minor things that are more of incremental improvements that generally mean the case we build today is better than the one we did last month and so on. Essentially what you buy today from us is the best we can do now and may be fundamentally the same as what we built last month but we know we got better because that's how we operate.
