Need Some Advice on Roster

[Swinagen]

Alright, so we're doing PPR in my league this year. My main goal for our league's format was to create a league that was more action-packed but also decreased the luck factor. The way I was hoping to do the roster was this:

 

1 QB

1 RB

2 RB/WR

2 WR

1 TE

1 Utility (any offensive player)

1 DEF

1 K

6 BE

 

I do have a few questions on this format, though:

 

1. Is having 2 in the RB/WR flex too many? Because coupling that with the regular slots and the utility, you could come across a team with 5 wideouts starting.

2. Is the utility spot a good idea or will it create imbalances with teams? I have no problems nixing it altogether. As stated earlier, I'm trying to create a league that's fast-paced but also one that decreases variance or luck. I'm guessing most players in our league would fill that Utility spot with a QB--in which case, what sort of scoring should I use for QBs to make for the most balanced scoring?

 

Thanks for your input, everyone.
