I have one with the standard stock that after 50+ rounds hasn't cracked. If it cracks, I'll get a synthetic stock for it. Logically, synthetic stock should be less prone to cracking but if mine cracks, I'd rather invest the extra $100 or so in a synthetic stock.
Even though I got the standard stock, it's quite pretty with a little figure. If it was much prettier, I wouldn't want to take it hunting.
