  A small subset of extragalactic double radio sources, termed HYMORS (HYbrid
MOrpholgy Radio Sources), is distinguished by a very unusual, hybrid morphology
in terms of the Fanaroff-Riley (FR) classification. In HYMORS, one radio lobe
appears edge-darkened (FR I), while the other shows a well-defined emission
peak near its outer edge (edge-brightened, FR II). Such sources are rare but
critical for constraining the mechanism responsible for the FR dichotomy, a
widely debated issue in extragalactic astrophysics. Here we highlight the need
for caution in assigning FR type, in view of some upcoming observational
campaigns to confirm HYMORS among the candidates. To illustrate this we
highlight the cases of 3 radio sources which have been perceived to be HYMORS,
including the radio galaxy 0500+630 (4C +63.07) which has been claimed to be a
good, original example of a HYMORS, with a FR I western lobe and a FR II
eastern lobe marked by a prominent terminal hot spot. However, its recent VLASS
map at 3 GHz has revealed that the western lobe actually extends much farther
out than reported and terminates in a well-defined emission peak. This implies
that the source is a regular FR II radio galaxy and not a HYMORS. We also
provide a brief perspective of the HYMORS phenomenon and underscore the need to
confirm a FR I classification by ruling out additional FR II characteristics,
such as an inward lobe-widening and spectral steepening, as well as a lack of
prominent radio jet within the lobe.
