She has a fairly flat back, with not much wither - the horse is “Diva” in my sig line for anyone curious. I was told by Lovett and Rickets that the Rubicon was on a Solstice tree it just had added features such as the adjustable billets etc.
I have looked at used Rubicon’s, but they just really aren’t out there, especially the Havana brown in all leather - and I have yet to find any with normal stirrup bars. Sigh.
