Ideal dynasty roster?

What is an ideal roster setup for a superflex dynasty league? How many of each starter spot? How bench spots and taxi squad spots? Thanks!

I like the rosters very deep. 1 QB, 2 RB, 2 WR, 1 TE, 3 Flex, 1 Superflex, 18 Bench, 10 Taxi

For my 10 team we do 1 qb, 2 rb, 3 wr, 1 te, 2 flex, 1 super flex, 20 bench, 3 taxi, 2 IR. This works out pretty well so there is decent waiver wire movement in the season
