I've been using the ISM (Touring model)saddle for 6 months and I can recommend it. It's not perfect, but it's by far my favorite noseless saddle (I've tried the Spongywonder, Spiderflex, and Moonsaddle). It doesn't feel as stable as a normal saddle, but those little stubs help give it a lot more stability than the other noseless saddles imo. As a gauge for stability, my max downhill speeds on a... 1. Brooks B17 standard saddle was 35mph, 2. ISM Touring is 27mph, and the other noseless saddles were only 15mph. Above those speeds and it started to exceed my comfort zone.
What I don't like about the saddle is the way it feels when I'm climbing. My sit bones tend to wobble around on those 2front pronge things. Every climb it will bug me for a minute or two, but then I forget about it and start to think about how tired my legs are getting
