Do the JB4, you'll love it. I'd say go with the new G5 ISO however if you want to save some cash and stick with the older G4 board i have a 15ohm for sale since I just upgraded to the G5 ISO. Either way definitely do JB4, that makes the biggest difference out of all the mods and you won't regret it.
