Sorry, I didn't see this thread.
I don't think it's your sychro. If it were a synchro you would grind going into first from second. Most likely it's linkage not allowing you to shift all the way into first. do you have a lift? transfer case drop? body lift?
Taking off in second gear would wear your clutch faster.
ETA: damn, I just read your other posts. I agree, sell it and move on...
