All depends on what sort of power delivery you want mate. If you want a aggressive setting then go for B9 T 5 or 6 and F9. Where as if you want a more progressive power, then something like B7 T 5 or 6 and F9. Either of which should see around the 300 mark or maybe just short.
Regarding the RR figures, it's generally JKM v's the rest of the world. But as TC says, it's only a figure and unless you have other Ed30's there with the same same mods to compare against, I wouldn't worry about it to much.... Trust me, it'll be quick!!!
If you do get it on the rollers, I would suggest you do as Red has mentioned and keep using the same RR each time, especially if more mods are added. Then you can gauge a more realistic figure in regards to what gain you make..
