Looking for Dynasty Startup Recommendations/Advice

Hello all,

I have been playing fantasy football for about 5 years now and I am very interested in starting up my own dynasty league with some of my fellow foot clan members. As this is my first time starting a dynasty league I am looking for some tips and pointers to make the league competitive. Is there any general rule of thumb when it comes to roster size, number of supplemental rounds for a rookie draft, and waiver periods?

I am accustomed to the generic rules for a redraft league and I’m wondering if there are any major differences in league setup that I should know about before starting this new dynasty league.

My current plan is:
Sleeper platform
Half point ppr
FAAB System
14 teams
8 team playoff
1 QB
2 RB
3 WR
2 Flex (WR/RB/TE)
1 DST
1 K
1 LB
1 DB
1 DL
