Brand new SF4 player, going to main Cammy, who else to learn?

Who else should I learn for a good spread of matchup?

Is Balrog a good choice for 2nd?

I have a Juri up my sleeve for the Bison and Balrog matchup (dat anti counterpick i know). She isn’t a counterpick for these characters but I generally feel at an advantage due to the huge amount of time I spent on these matchups with her. Shes also incredibly good against Zangief and Thawk.

I would say Seth combos similarly
cr. lp, cr. lp, cr. mp xx special
cr. lp, st. lp/lk, cr. lp, cr. mp. xx special
timing is quite similar to Cammy
