Greg, really? You had the Bank Roll earlier than the Bank? From my POV, the Bank is longer than the Bank Roll due to coverstock and surface prep.

I would have thought that the RB would be like the Bank Roll, and the Stampede would be like the Bank, due to the increased backend. Interesting.

On another note, the Euphoria looks a lot like this weightblock...

For me, and that's for me, Bank rolled like the Raging Bull. Bank roll was still heavy but more in the later part of lane, hence the Stampede comparison. Others with different roll might see something different. If  you see them opposite, then just switch it around. I've shot well with all of those balls, including 900global so u can't go wrong with either OG Bull, or Stampede.
