I just got the traditional bug a few months ago. I decided to drag out my old Black Bear bowfishing bow to play with while I wait on my longbow to be made. I didn't have a tab, so I dug into my leather supply (I'm a falconer so I keep some handy). I cut out a thin tab from kangaroo leather. I just wanted something to use until I could decide on what tab I wanted to buy. After a couple of months of shooting it, I don't see any reason to "upgrade". It's simple, works great, and is easily replaced if I ever wear it out. Kangaroo leather is very tough and stretch resistant though, which is why we use it for jesses and anklets in falconry.
I made my tab similar to the Teaschner tabs mentioned above, except I didn't have any snaps at the time, so I put a rivet where his snap is, and just used a loop of paracord where his rubber o-ring is. I can adjust the size of the loop by the knot.
