It seem Royalex hulls are always differ from their composite versions. This goes back to the Mad River Explorer, which was shorter with blunter ends and less V in RX than in composite.
It is also true of Argosy, Cascade and Wilderness and the Mad River Guide/ Freedom as well as Bell's offerings. Of course those variations pale into insignificance when looking at Hemlock's composite Shaman and the Mohawk RX version.
The RX WildFire had do differ from the Composite because the abrupt shoulders wouldn't release from a vacuum forming mold, and of course the RX sandwich cannot bend to yield as tight an entry line. That we also halved the stern rocker doesn't seem to be a moral sin, hell, everything else was different, we were trying to improve performance for an entry level market. [RX was ~half the Kev price.]
The name change had to do with contractual arrangements. Bell de-emphasized the Wild in favor of the composite YS Solo because they owed fewer royalties for YSS.
It's probably not worth getting to exercised about which $0.50 decal got stuck on a canoe. There is more variation between other Comp[/VFRX hulls by several other manufacturers.
In the beginning there wss one WildFire mold; 14 'X30", symmetrical 2.5" rocker. There is also just one vacuum forming mold for a similar RX hull with differential rocker, length maintained but shoulders softened and a single mold for a differentially rocker composite variant with higher shoulders.
