Let's see, bike and rider with a combined weigh of 250 lbs impacting a large pot hole at 30 mph? I doubt that a high quality custom wheel can survive this collision. You're lucky that you didn't flip over and end up on the obituary list. You need to rebuilt the wheel. Stick with 32 h or 36 h wheel for optimum performance. If $ is tight, then you can re-use the old 28 h hub. It apparently was strong enough for daily use until that impact. Make sure the work is done by a good wheelsmith.
