That's the one. Put Parklands and Pap Redwood in there in place of Cashmere & 1102CF then play the PDL as a reserve grade for that league and you should have every up and coming young player in ChCh covered. Burwood could take the place of a PDL from Ashvegas if they weren't up to it numbers and finance wise.
Agree 100% - give div1 clubs first option to have a mirror PDL slot alongside their 1st team, and fill the rest up with those that don't have one. As long as it is a true PDL, than u21 teams could fit in there quite nicely, AND the team that comes out on top at the end of the season already has a structure in place that is aligned with MPL/MPL.
