You're not playing devil's advocate, you're just reiterating my point :-)

Using custom tables over CPTs makes sense in the scenario you described.
 You're trying to filter/match/sort by multiple meta fields which, on a
high-traffic site, *will* impact performance.  It's one of the **very few**
situations where I would advocate custom tables.
