Believe it or not, and this should go into Ripleys Believe It or Not! it is entirely on topic.
I have a black ultra centred on 16e and a black ultra on 13e because I needed a long neck to get past the 16e and an mti on the other side. Now 16e is stronger I was thinking of using an Inverto Premium with the smaller 40mm cap on 16e but if the red rocket is a better performer then it would be better for the feeds, on 16e some can still be weak.
Also I have an offset 23e elsewhere and it is old and crap and at a odd angle and the red rocket could do the job very nicely.
Assuming of course it doesn't turn out to be over hyped like the last one.
There is also the Best LNB if the red rocket turns out to be less than stellar.

The hmsat page is interesting. The OP SE is not our OP. It looks to me like the OP SE is designed with a massive hollow feed arm for use high up to resist wind deflection and to stop snow and ice accumulation it falls through the gap. Being metal a heating element can be taped round in a square on the back. It wouldn't be my first choice for use at exposed heights in this country but it certainly would be good for use in the alps.
