If their is a store variant with a better cover than than the standard issue, than that's the one I will chase every time... I don't care about value, but a good cover on a key issue especially is far more appealing to me than the same comic from the standard print run with a mediocre cover .
As long as there are others like me who are willing to pay for great covers, I don't see good store variants crashing.. Those who purchase store variants, 1:100 etc solely speculating value on scarcity - that could have a rebalance is there is a bit of a flood.
