I wouldn't recommend people building any 7-bolts. But I am a cheap ass who didn't want to buy a bunch of new parts for a 6-bolt. I also think that any 7-bolt that crankwalks very soon after being built didn't crankwalk from the traditional 7-bolt reasons. It took most 7-bolts 2.0ls 60,000-100,000miles to crankwalk. When a newly built 6-bolt crankwalks, and it does happen, nobody trys to instantly blame it on it just being a 6-bolt. But if a newly built 7-bolt crankwalks, everybody just assumes it's because its a 7-bolt.
