Pairings that don't get enough stories

There are plenty of pairings in the fandom that people have come to adopt, such as TwiDash, Sparity, and FlutterMac. And they all have plenty of fanfiction to keep their fans entertained (Even if some of those stories tend to get a little…lewd.).
 
However, there are other MLP pairings that don’t receive a lot of attention from fanfic writers, despite the massive fanbases those pairings have. So, if any of you have a pairing that you feel doesn’t get a lot of fanfics written about them, feel free to share them in this thread.

SoarFire.  
(for some reason peoples like Soarinbow or Soarinjack)
 
PokeyPie
 
FlutterMacilee
 
RariSpilight
 
ButtonBelle

Thorax x Spike

LunaShy

Pinkielestia and Trixiepie.

I forgot to mention this in my original post, but the pairing that I feel doesn’t get enough love fanfic-wise is FleetMac (This is the only story I could find of it.).
