Yes, very pleased with how the floor feels now. The 2x4 solution was absolutely the easiest and best approach to cure the bounce in my floors at this house as it is almost completely gone. You wouldn't even know it is there unless you are walking around trying to notice it, and this is with the hardwood flooring. Getting ready to install some cheap carpet on top, which will make it a non-issue. Hopefully this house will be sold in the next 60 to 90 days, so I can move onto other projects.
