Scrolling RA set for Xenon

So Im sure most people would tell me to iCoG (or chaos/goodness in general) And I am farming 20 of them from the attendance. What I want to know is if I should toss on a 50% armor unleashed first (+3 all stat). My reason for this being the RA set only adds 2 stats (my pirate adds str/dex), so if I toss on a 50% unleashed it could also add some luk as well. Would this be a good Idea? Right now, I have 5 slots on my top, 6 on my bottom, and 12 on my hat (23 total, and if I was to hammer 29 total) Since i will only get 20 iCoG should I use unleashed scrolls first? Or possibly try regular or incredible chaos with return scrolls? Im open to any advice and help, thanks!
