Just following-up with my own review of WOW saddles - so future searches can learn from my (successful!) experience. 
After months of comparing options, scheduling trials of many different brands, and finally taking the plunge…I now own a WOW saddle. I’ve been riding in it 3-4 days a week for 2 months - and love it!
As a hunter/equitation rider (although I “dabble” in other disciplines), it was very important to me that I got something that “looks” right for hunters, along with being supportive and fitting my horse - as I didn’t want it to be noticeably different when I go to h/j shows. Thankfully, my saddle fitter is wonderful and worked really hard to have the right combination built. It’s perfect!
I ended up with the “Jumping Fixed Block” flap (has calf and thigh blocks built-in), “Continental” seat with channel, and the whole seat/flap are is in nubuck leather (so grippy!). The bonus? - I can do BOTH a traditional (long) girth AND a monoflap (dressage) girth. This last part was a result of some “experimenting” by my saddle fitter - and works great! Ultimately, I have both types of billets, and it’s just a < 5 min swap to remove the dressage billets when I want my traditional girth (for my hunter shows). The rest of the time, I get the benefits of a monoflap! Also, my WOW is wool-flocked (not the air system). This was important to me, and my saddle fitter / WOW rep also preferred wool-flocked, so that was an easy decision. 
So, summary of my favorite parts:
(1) the perfect fit for my horse & the ability to easily (& inexpensively!) change it as he grows - he’s only 6 & is a warmblood, so knowing I can easily swap out the headplate and/or panels as he changes shape is huge! I ride in just a thin square pad and there are absolutely no pressure points, sweat marks are totally even, etc - better fit than any other custom brands I tried.
(2) the support it gives me on the flat and O/F (my poor ammy body can’t do it alone!) having been able to customize exactly which blocks and seat I wanted - even better support than any of the other saddle brands I tried, including top-of-the-line custom brands.
(3) that I can switch from a traditional Hunter (long) girth to a monoflap/dressage girth in < 5min all by myself!
In just our short summer together, this saddle has proven itself in the hunter/eq show ring, going cross-country, riding on the beach, and as we work on building Ari’s frame. Worth every moment of research and every dollar I spent. THANK YOU, David Gilpin & WOW!
