All I can see is it's a nice idea and makes for a pretty display, but other than that, I haven't had much luck with the pick'n'pull blocks. The item(s) I transport always end up sliding under the top layer and are only held in check by the inner sides of the case itself ... even after using spray adhesive. This replacement convoluted Cobra Foam fits the Apache 9800 very well and helps to hold even my heaviest and most bulky item(s) securely, the same as any other hard case I've ever had. I don't know how this foam will deteriorate over time; if it should last as long as the cases it is replacing, I can look forward to about 40 years of service. Long enough to where it really won't matter much to me. Don't fool with the pick'n'pull blocks or else plan on ordering a Cobra Foam replacement.
