Optimal 10 Team Redraft League Roster Settings

Hi, I’m starting a 10 Team Redraft Superflex League (0.5PPR, 0.25 PPFD, 5 PPaTD), and I’m trying to pick the best roster setup. I don’t want to create TOO much scarcity, so that people who didn’t draft perfectly don’t even have a chance, but I also don’t want there to be too little scarcity, where most players are like 85% replaceable at any given time.

Differences from #1 are bolded for ease of identification:

  1. 1QB, 2RB, 2WR, 1TE, 1Superflex (Q,R,W,T), 1D, 6Bench, 1IR (15 total)
  2. 1QB, 2RB, 2WR, 1TE, 1Superflex (Q,R,W,T), 1Flex(R,W,T), 1D, 6Bench, 1IR (16 total)
  3. 1QB, 2RB, 3WR, 1TE, 1Superflex (Q,R,W,T), 1D, 6Bench, 1IR (16 total)
  4. 1QB, 2RB, 3WR, 1TE, 1Superflex (Q,R,W,T), 1Flex (R,W,T), 1D, 6Bench, 1IR (17 total)

5 - 8. The above choices in order, but just with 5 bench spots instead of 6 to avoid as much stashing.

Which one of these would you guys suggest?
Is there another setup I’m ignoring that you’d suggest instead?
