Not that I think Achetype racks are all that stable either (nor, ulitmately, is the Synergy Twin which I own, compared with a truly stable non-adjustable rack like a Billy Bags or similar), but George's home-brew experience was undoubtedly further compromised because Salamander prefers to make the Achetype design not with MDF shelves, but solid hardwood. Personally, I've been thinking of making some replacement shelves for my Synergy, either out of hardwood (the top and bottom are already maple), or high-density particle board, or perhaps 1/2" HDPB laminated to 1/2" MDF and covered in matte black, Formica-type high-pressure laminate to create somewhat of a constrained-layer sandwich with dissimilar resonant properties (or at least a greater resistance to chipping!).
