How many Kitasans is worth abandoning this roster for?

I dumped 90 rolls and got zero Kitasans and just one extra Sweep Tosho but i did get a Vodka and two speed SSRs that i have no idea match up with other speed SRs

As pathetic as it is, getting 4 SSRs in 90 pulls is above par... this is my account overall. i should just move on right?
