Glenn,
There is a guy asking how to correct the size and angles on a 5" pocket.
I recommended you because you have the most knowledge of how a Pocket should play.
Please see his post and see if you can help him out.
He's just a private CGIV table owner that wants to verify his pockets are built correctly. He says he is willing to pay for your time.

How a pocket 'Should' play is all a matter of opinion.. You have stated that Glen has "the most knowledge of how a pocket should play", though that statement is flawed. How could anyone have 'the most knowledge of how a pocket should play'? Some just have stronger opinions than others. Glen has the knowledge of table construction and the resultant effects of pocket design to form his opinion. But, it is still just an opinion.
Gather 100 pool players in a room, and they will likely all have a different opinion. Glen is no different, regardless of the knowledge that he has.
With that being said, here is my opinion:
You can really change the way that a pocket plays, simply by changing the angles or hardness of the facings. Having said that, I like to keep my angles consistent, regardless of mouth opening. I also prefer the use of 3/16" 60A neoprene facings. Harder facings tend to make the pocket play too dead for my liking. Softer facings will rattle balls excessively, or have a tendency to fire rejected balls across the table. I hate that.
For a Brunswick table, I generally prefer a 4 3/4" pocket, at 141° x 12°. The 12° downward angle will accept well hit balls, but may hang those which are poorly hit. If you want it to play a little tougher, tighten the opening to 4 1/2". If you want it to play easier, increase the downward angle to 13-14°.
Glen's test for an acceptable pocket is to freeze a 3 ball combination to the long rail. Shoot at it, and fire the combination down the rail, into the pocket. A good playing pocket 'should' accept that ball.
Keep in mind, the cleanliness of the cloth will have a huge effect on how a pocket plays. Dirty cloth always makes the pockets play tighter. Fresh cloth will make even tough pockets play like buckets.
