FS weapon choice help

OK right now i have a tit. kat 30%cdi... not good at all+8
but should i get FORCY+11 10%cdi 400m
FORCY+6 20%cdi 300m
FORCY+9 7%amp 255m

For my lvl my atk is low its only 821=( but cdi with current kat i have 172 cdi with 52 cr
i need help do i need to get to 900 atk if i get the +11 bit pricey for a katana but i can afford it im thinking about getting a K board to get my amp and make up the loss of cdi by switching from tit. to forcy
so my question is more atk? more amp? or more cdi? or all? what is necassary for a lvl 165 FS like me
i pvp more but can solo ic1 so def really isnt a problem my amp is 43% i have all the offensive upgrades i put all my points to str so i just need new equips so just need a new katana or blade i dont wanna replace my lycanus crystal cuz it has +7% amp with 17% cdi i have merg ring im getting a slotted bof+3 so i get +8% amp any helpfull tips will be appreciated thanks.
