How long does that 100+ STR last? How long can he sustain that level of damage without tremendous resource expenditure? Could a reasonably motivated veteran player maintain that level of damage through their normal questing, or even for every boss fight? If the answer is no, then you're shooting all of us in the foot.
Best case scenario results aren't a viable average for integrity of play. If you're going to use best-case averages, please post ungeared, un-buffed averages for the same character with the same base stats and feats to have a worst case average to represent the opposite end of the bell curve.
