I'd say don't worry about the plus on the cruiser. What you want to do is get as much damage as possible. First up you'll want a decent bow. Worry about your set after that. You aren't going to be tanking many hits, so even a plus 0 set would be fine as long as you have some buffs. Assuming cash wasn't an issue, for a bj I'd try to buy a suit with a decent attack piercing then buy lots of clean parts and awaken them. A dex+ helm, attack+ gloves, and crit damage boots would be a big help, and the parts are cheap enough clean to awaken enough of them to get some nice results.
