a close friend went to Africa two years ago. A week before the trip he broke his wrist and it was doubtful he could even shoot, let alone sharpen broadheads but heck, everything was paid for already...so he bought 18 Phantom 125's..put brass inserts in his shafts, mounted them (very sharp out of the pack he said) and headed out.
Long story short- 7 animals- 7 shots- all recovered- including two kudu bulls and a wildebeest so I guess you could say he was pretty happy with the results...one of the kudu was spot and stalk, shot as it galloped off at 25 yards through the heart, quartering away!
