I agree with Tom6897. I have done the Flexy. Its simple design encourages upgrades and tweeking. Unfortunately it is not a good design and is ironically beyond improving with "upgrades" like brass rods. Ikea's lack table is much better, although I am not completely sure they are made the same way. They are cheap enough to buy one for experimentation. If you flexy, don't use MDF. It sounds bad, period.
