Crusty,
Remember that for a lot of those years, Lane #1 wasn't product-registered, either.
I see a similar discussion going on right now about Elite now that Robert Smith dropped them (and they will apparently drop their registration at year's end). Some people are talking about Elite being "junk." If Elite is junk, so is Brunswick, because that's pretty much what those balls are. Elite is way overpriced, but is not junk.
The versatility argument is fair. In the Brunswick days, you had two basic looks, the roll-heavy look from the Diamond cores and the more angular look from the Bomb cores.
I think the versatility is greater now that they've moved to 900Global for coverstocks, based on what I've seen from what I've drilled recently. They now have six different cores in production if the XP is still being made. So I expect that to get better.
