My contribution to the thread:
LM Products X-Clef Worn Leather strap-bought it from
Sweetwater a year ago. I didn't like the chemical smell of the foam padding so I put it out in the garage to off-gas. I probably should have returned it but then I gave it a relative of mine. I asked to check it out again and trying it I found it's not going to work for me.
Pros:
-chemical smell dissipated over time
-very thick padding
Cons (IMO):
-the padding is so thick that the strap is stiff. You can only fold it at the metal loop connector.
-maybe it's my own pickiness but I feel the metal loop that connects the adjustment strap on my back
-the smooth underside slides around on my shoulder
-some reviewers note that the strap is not for tall players. I am short and I had the adjustment at its shortest length. There is only one strap hole and I could have shortened it even more!
I had high hopes for this as it was very well padded and not too expensive so it was a disappointment. Onto the next strap!
