Thank you for your kind words, Justin - and the example to compare with!
When the flowers first opened, I was slightly (only very, very slightly!) disappointed regarding the size, but immediately took a liking to both its colours, stance and form.

Do you happen to know more about the genealogi of this cross?
I've seen a discussion as to wether 'Sam's Choice' is Val x MM or Rex x MM - the latter position makes sense, when seeing the (still) slightly bicoloured pouch and the 'petiteness' of the flowers; the former allegedly is based on information from Sam (and one would suppose he should know as the choice was after all his?!).
Might 'MM Best' be a selfing of MM?
Hope you - or some other Roth specialist in these page can contribute with an answer?
Sam's Choice is Rex X Mont Millais. As @Paphman910 mentioned MM Best is MM x self. I have another cross Rex Jr. (Rex x self) x MM Best. I have only bloomed one so far, but the MM Best parent was dominant.

What type of media are you using?
I grow my Paphs in Greenmix (as a window sill grower it seems to help me keep the humidity up - albeit I'm still a bit handicapped in this respect, when compared to the lucky owners of a greenhouse).

"GreenMix for Orchids is a mixture of water-repellent and water-absorbent granulate with added perlite and lignite. The granulate is made from stonewool, the basic element of which is diabase rock. GreenMix for orchids is produced by Grodania A/S" (and was developed in cooperation with our local mastergrower, Hans Christiansen of Orchidegartneriet in Fredensborg: Online salg af orkideer | Stort udvalg af alle former for orkideer).

The one thing you have to really beware of with this growth medium is never to let it dry out completely, as this would be detrimental to the roots. Interestingly is it, that plants, that normally need a dry(er) resting periode, f.ex. Dendrobium, grow and flower perfectly without this change in culture, when grown in Greenmix.

The plant in this thread is grown in an east-south-east facing window...at room temperature, i.e. mainly around 18-23 degrees celsius. Though on hot summerdays, especially during summer heatwaves, the temperature can sometimes go over 30 °C.

Paphs thrive best when given rain water. But as I live on the 5th floor in an appartment complex, this is out of the question. I've found a viable alternative, though, and use 3/4 spring water + 1/4 tap water (NB. tap water in Denmark is quite clean and you can drink water directly from the tap).

Paphs, I fertilise 1-2 times a month, except nov-jan (quite dark months up here north), with Pokon 20-20-20 (NPK 20-20-20 + Molybdenum (MO) 0,0005% Bor (B) 0,0200%, Kobber (CU) 0,0500%, Jern (FE) 0,1000%, Mangan (MN) 0,0500%, Zink (ZN) 0,0500%). (Phalaenopsis, Bulbophyllum and Cattleyas are fertilized more frequent).
In the summertime, where the light intensity can be high, even on these latitudes, I add, once a month or so, a wee bit of Epsom salt to the fertilizer.

Kind regards,
Jens

Jens, I can just join in the choir. These flowers are excellent in all and as you know....size is sometimes helpful but it isn't all. 👌

The sepal almost perfectly mirrors the dorsal......
These were my thoughts, too.
