Have you checked other table manufacturers offerings here in 2024 and how they are built? If you do a search in this forum the real pool table mechanics, who work on pool tables for money always seem to agree that the table's structural design is where it all begins. I have never played on a GC V, but I am sure they are great tables to play on when setup properly. The GC is a wood framed piece used to hold up the slates, where other tables use a metal frame and engineered wood to hold up the slates. The Rasson Ox uses a metal frame and aluminum prefabricated adjustment slab to support the slate pieces. A new GC V is a good sized investment and it might be best to find a billiard supply or pool room that does have a GC V in their mix and play on the table for a few hours. You will get a feel for the table to see if it is to your liking, along with seeing how a properly installed GC V is supposed to play. You can then have a basis on weather your new GC V home install is done correctly.
