Regarding weight, the Moses design differs from the Modulus necks in that the Moses necks are solid while the Modulus are hollow. I have both and prefer the Modulus partly because of the weight difference. But the Moses necks are nice, too. Since Moses stopped making necks a few years ago, there have been none on the market until a company called Klos recently started making a 3x3 guitar neck as well as a Fender Strat neck. I know nothing about their design or quality.
