Some additional info that might be helpful...
I'm 185 pounds and live in the mountains of central Arizona, just west of Sedona and north of Phoenix.
Our riding here is lots of rocks, trails with lots of direction changes and/or punchy climbs, a fair amount of climbing at times, and some rough and ready trails if you know where to look.
I'm definitely not afraid to try different shocks or forks as I figure that if I have tried lots of things I will have a better idea of what I like and what works.
If I had to do it all over again I would definitely go with the Mod based on what I know from using it and based on using some other shocks in the past year and change (11.6, Storia, TTX, Fox X2 air, Mara Pro).
It isn't easy to find lots of information about the Mod and for me the decision maker was that I have lots of time on all of the Selva variations and really like how Formula stuff feels and works so having those ideas or characteristics in a shock was really appealing to me but they aren't always easy to find here in the US which is why I reached out to Alba.
