I've shot a recurve that had Limbsavers on it, but not a longbow. I'd imagine if you wanted to use them on a longbow they'd go just above the fadeouts at each end of the riser.I didn't think they did much, if anything, with the recurve, so don't be expecting too much.
By the way, it ain't just you. I haven'tbeen able to get the flippin' search function to work ever since they updated the software.
