If you're fury/rabies, then shape skillers are the best option. But I guess you are fury only, then I think ar/life scs should be best, or even 3/20/20 if you can afford but I dunno if that is better. Personally I would use 36ar/20life small charms as ar is very important. You can also use 77ar/35life large charms which almost gives the same as two scs.
