Dynasty league setup (1 Viewer)

Starting a super flex dynasty league and trying to decide on lineups and looking for imput from anyone who has been in bigger leagues. It will be a 12 team league with .5ppr and .3 te ppr premium with 6pts for all Tds. We are looking at

1Qb

1 Superflex

2 rb

5 wr/te as we are combining WR and TE

The question is should be do 2 or 3 flex spots and start 9 or 10 none QBs a we assume most will start a QB at Superflex. Are there enough players to need to start 10 none QBs or will it take the fun out of it.

You can adjust scoring so that a QB is not an auto start at SF.  That would be my suggestion....try and make scoring across positions equal (or as equal as possible) so that there is variability in lineup construction.
