I was reading the discussion about adding weight that's back a few pages (on p ~156). I notice most setup sheets and many people here mention putting 3 oz behind the battery. But most/all of those setup sheets and people are running mod (well, higher kV than a 17.5). All this to ask:

Anyone here running this much weight behind the battery with 17.5 blinky? Any other suggestions (indoor track, high grip clay) for a good starting point? Obviously, I'll try some options myself, but just want to get some feedback from some experienced blinky drivers.
