Brunsw. vs Diamond
FIRST!
(always wanted to do that)
I'm in a dilemma (not unlike you Al) that has forced me to play on both GC's and Diamonds. And yes, playing straight pool on a Diamond is more difficult given all variables being even - same cloth type, same pocket opening width, etc. My dilemma is that there are 2 rooms nearby that have 20-22 GC's. However, the room owners really don't take professional care of the tables. ie unlevel tables, uneven rails, rails still covered with 80/20 felt while the bed is Simonis, no ball polisher, no lines on the table for 14.1 players. In addition to this, these rooms don't have a daily rate. So playing 20 hours of pool a week at 4.50 an hour comes to 4.5 x 80...carry the 1...360 samolians a month. They're recreational rooms for high school kids and bangers mainly.
Now there's a 3rd room nearby that offers an $8 daily rate from 11-6 everyday, the tables are in 95-99% shape all the time. Here's where the dilemma comes in...they're Diamonds! So, I bit the bullet for the longest time and shelled out thousands to play on GC's until about 3 months ago. Hey, I have bills too, so instead of continuously handing over a good portion of my check to the GC room owners, I started playing on the Diamonds. When I say this I mean it - I HATED Diamond table up till about 3 weeks ago. You really have to spend a few months getting used to playing on them after a lifetime of playing on GC's, but when you do they're not too bad. You won't play as well as you did on a GC. Won't have as high a run on them, but they're not 100% bad. This is only MY opinion of them, but there has been many other discussions of a similar nature in other rooms.
The differences that I see; the pocket shelf is a little deeper. A ball that would barely drop on a GC will sit in the jaws and smile back at you on a Diamond. A second difference is the cushion angle is different from a GC to a Diamond, causing balls to come off the cushion at a different angle. Diamond has finally offered a "fix" for this and if you're interested seek out RealKingCobra on AZ as he's a table mechanic that performs these fixes. And no, it's not something you can do yourself - it requires special tools and the process is top secret. I believe if you're allowed to see the fix process take place you have to sign paperwork stating you won't divulge the method. I'm totally serious. And I think that's about it. But there's a whole lot of threads in the Main Forum that have addressed this difference and a lot of knowledgeable folks who have chimed in, so if you're curious just do a search.
High run on a GC: 80
High run on a Diamond: 54
Although I did have a 53 on a double shimmed Diamond yesterday. And that's like a 200 on a GC!
