Hi, as i have said i have a 97 rogue with sneaky attack but also have money to buy shadow strike. should i buy? i think i should. if i do should i switch with sneaky or keep both?

Yes, buy SS. Use both. You can still cast sneaky at the very start of the fight even if the mob is targeting you ( you have to use sneaky on the mob from further away before it aggros onto you, and you will be able to finish casting it even if you starts taking damage from that mob)
