if you don't like the thickness, way it raises up the back due to having 2 layers, look into RAF or 3 ring Zulus.
I personally like natos. square keepers look cool and I like how it raise the back of the watch off my wrist a bit. more comfy for me, depending on the watch of course.
secure, cheap, fun, and I like that it gives a tool watch that extra "toolness".
I have been a bracelet guy for a long time but getting deeper into military watches as of late, nylon strap is becoming my latest obsession/madness...
