This is the first I've read of busted seams in like 4 years of reading. I didn't realize it was a problem. I've done it hundreds of times and never had an issue. I've never really paid attention to the level of boiling. I have even on several occasions thrown the complete frozen bag in the water and let it come up to boil, then boil another five minutes or so and it is great.
My bags aren't stuff to the seems though. Usually plenty of room. I don't know if this is the difference? I also use the generic bags, from the which website is currently the cheapest (rotates). Maybe this is the difference?
Anyway, I do find that boil in bag results in the best reheating results. I wouldn't let the odds of one bag failing every so often persuade you to try other less good methods. Just always have a freezer full, and you'll be fine.
