Alrighty then...I have struggled back and forth on which way to lay my boards. I (read: my wife) have decided to run parallel to the joists. Therefore I will be putting down the additional 1/2" ply + 3/4" hardwood flooring. (thanks for all the advice)
I now have to deal with one issue, additional height of the 1/2" ply that I will be putting down. but I have an idea...
Issue: The additional 1/2" will make it very difficult to replace/service the dishwasher due to the legs on it not quite clearing the height of the ply and hardwood (3/4").
Possible solution:
1) lift the counter top when replacing/servicing
or
2) why can't I prepare my floor for future board removal right in front of my dishwasher?
Refer to pic below: What if one board to the right most spot infront of the dishwasher was put in "loose". Perhaps cut the bottom of the groove side and loose fit it. The boards to the left of that board all the way to the left side of the dishwasher would be "screwed in" instead of "stapled".
That way when I need to service/replace the dishwasher, I pull the "loose" board, remove screws and pull other boards.
Will such an idea work?
