I bought those on your recommendation (along with the crimper tool) and did like them better than the Ancor ones. Now it's time to re-stock and so I looked at the FTZ in your link. Do you like them better now (or maybe the Sailors Solutions one were FTZ, I don't remember them being branded). Certainly wouldn't mind supporting SBO since they provide the forum(s). (Note: Maybe in front of my nose and I missed it, but I couldn't see how many were in a "bag"?)
BTW, I just compounded/polished/waxed my boat according to guidelines/products you posted on the web. Boat looks fabulous now My shoulders will recover, I'm sure
