Auction League 2 Flex question

Doing a 12 team auction league (normal $200 budget) and we replaced the kicker with an extra flex.
Havent found any sample budgets with 2 flex spots, any insight on how much you would spend on those flex spots or roster construction in general? Thoughts on the below? Any help would be appreciated!

QB $3
RB $40
RB $30
WR $40
WR $30
FLX $20
FLX $10
TE $5
DST $1
6 BN $21(couple $1s, a $5 and a $10?)
1 IR
