One or two hanging most routes at the Red means a half grade (or a whole grade)easier than redpointing, so I don't suggest a grade unless I have sent it. I can barely redpoint 12a, but I can easily lead Gong Ho, Tissue Tiger, Tuna Town, Chainsaw, Bare Metal with a hang or two and not even break a sweat. Sending them is infinitely more difficult.
Hauling a big ego up a route adds at least a full grade.
