I personally don’t think there’s a right or wrong answer to this, and ultimately it’s totally a subjective decision.
Prices wise, based on my sz 9 SX prices, you’d be trading like $1300-$1500 worth of pairs for a single pair worth like $1100.
But, the facts I think that we all can agree on in making whatever decision you make is that in the Muslins OW 5s we have a pair collaborated by a now deceased, iconic (some like more than others, but he’s iconic nonetheless) designer, that I wouldn’t be surprised if they never re-release, and due to all these factors are probably going to continue to rise in price, and be harder and harder to obtain/find as well. On the other hand you have the Blk/Red 4s, Infrared 6s, and WC/BC 3s, three iconic J models that have already re-released a bunch of times since their original releases, and there’s no indication that they won’t continue to re-release periodically in perpetuity.
With these facts in mind though, like I said earlier, I don’t think there’s a right or wrong decision to make, just however you feel.
