I have that sporran, though I did not buy it from Stillwater.

I like it a lot. Plenty of room for wallet, car keys and cell phone, and it looks sharp.

I guess I never thought about it being stiff, but then, I never understood the attraction of sporrans that look like the sacks you see at Ren Faires.

It DOES drum. I like the drumming, but some guys stick the tassles down with a bit of silicone.
