The closeness between the two clubs, both geographically and organisationally, makes this pretty much a no brainer. My only reservation is the way in which these two way deals seem to function.
As I understand it, players on a two way would only be able to play for the devils if the Pitbulls weren't playing. One scenario I can imagine is the devils carrying injuries and needing extra bodies, so wanting to call done players up - as happens between NHL clubs and affiliates. In this situation the devils wouldn't be able to do this, if the Pitbulls were playing. That not only denies the devils benefit from the arrangement, it denies the players themselves an opportunity. As an illustration for this, how often was harewood permitted to play up?
This, to me, is the flaw in the relationship between the various leagues. We should be able to call up from Bristol, and they should be able to call up from the league below them.
