Yeah Merwin's is most definitely on the up and up. A bit more low key than France44 which is a very good thing. WET came and want so fast on 44 that most people assumed it never went up which could be what happened with Abrasive.
Merwin's has Abrasive in stock now.

Just received mine today. Tastes so good it makes me want to learn to brew just so I can make nothing but this. That's kinda how I found this thread....
