Well, you are four levels away from the L79 Burners. But with starter balls the meter will be very, very, fast.
If you can't consistently hit--or get close-to the ding, that sort of defeats the high precision rating, forgiveness will only compensate so much, and it really is easy to be waaay off with a super fast meter.
So it's between the G20 and the Burners. I'd say go with a meter speed you'll be comfortable with in the long run. Some diss the Rocketballz but I like them. Worth a rental to check them out as well.
I really like the L47 Raptures but you are at a point where you can skip over these medium level clubs.
