Is it better off to just straight out stack strength for this ws? Would wearing the ferine gausape +2 and trying to stack the killer effect bonus be a good idea? Would beast trousers +1 (with its added killer effects %) be on par with avant cuisses (the nq)?

I played around with 5/5 ruinator on em/t verglas golems (mostly because I know what my rampage looks like on them) and there still seemed to be a wide range of damage (from 1400 low to 3100 high with rr/apoc/mounted champ, my standard bst set in Abyssea) so I'm not sure I would call it a "consistent" ws. Does ruinator crit or double attack?

Sorry for all the questions but I really want to make a good ws set for this and I'm not familiar with all ins-and-outs of it yet.
