azstoneconsulting, I was reading the comments you made regarding counterbalance island bracketts on their web site and you mention that MIA recommends marine quality plywood, although it is an overkill. I called the local Lowe's and talked to the manager, they can special order marine quality 5/8" for $73.53 and special order 5/8" ACX plywood for $48.88. The cost difference is not enormous, do you think it would be better to use the marine quality? I know nothing about marine quality and have not even seen it, is is harder to cut? Does it give? Sometimes more expensive is not better for the situation. After all that I have been through regarding this counter top, I want to make sure I never have to do it again!
