anyone here use these? ive seen some used ones pop up here and there. ive used the original max series and still have a 683. r the newer ones much improved over the original max line?

The new max 3d is supposed to be a touch better than the endurance series. Which is better than the original max series.

I only have one Max 3D so far but I find them to be much improved over the original series. I'm a big Powell fan so I plan to pick up 3 or 4 more 3D rods in the near future.
