Availability is the main subject here, working on resolving a problem and being able to supply demand is two different subjects. Brunswicks GC4 drop pockets are the best pockets they've ever made, but Brunswick is not going to supply them to every older GC owner at wholesale cost just to resolve the plastic left on a players shaft from useing the pocket as a bridge.....its called improvements over time, not go back in time and upgrade or modify everything already built and sold in the past. I hace customers that have red lable Diamonds 10 years old that want the blue lable rails now, and feel Diamond should replace the rails at cost....because Diamond made a change in their rails.....so what, changes take place, just not always before someone buys a pool table.
