I'm talking TNT. I'm talking about something I've already done. Go to http://www.elusivedisc.com/prodinfo.asp?number=HW-A1216
There you will see what I am talking about. However they want to sell you new "cups" at the 4 corners of the TNT. But all you really need is what is shown with the ball on top. The ball will rest against the top of the cups you already have but you may have to experiment with spacers. I made spacers out of wood. Under the ball there are two plastic parts that screw together allowing adjustment for height.
This is the arrangement that VPI has used to replace the bladders on the high end TNTs. It works great.
