I classify VALite with the Japanese carbon-manganese tubesets, such as Ishiwata's Magny series, Miyata Mangalight and Tange Mangaloy. They all came out during the same era and bridged the gap between hi-tensile and CrMo in terms of cost, ease of brazing, tensile strength and consequently, frame weight.
While the exact compositions of these tubesets are unknown, they are likely similar. It would not surprise if VALIte was re-branded Magny, given the close relationship between Fuji and Ishiwata, and the fact the gauges for their respective triple and quad butted sets are identical.
