My own custom board (fiberboard 24" by 48") has never quite performed the way I would like it. I have spent some time recently, trying to get it working correctly, but the board is still not where I want it to be. I have a 620 that outperforms it.

I am sure if I could get my board to run the way the 620 does, I would use it always.

I think that the closer you get to the true proportions of real football, the better.
