Yes, on the slow end of slow flight is what they're for, and the only place they really do much. When operating in the slow end, a cub's tail gets baggy.... no big deal, everything works, and it is a good indicator of how close to falling off you are, but with the gap seals on it tightens back up and gets almost as sensitive and tight as it was in cruise. On some cubs the difference is about as subtle as adding vg's. So not everybody (or every airplane) is going to notice a big change. Like vg's a cub will do everything just fine without them, like vg's some swear by them, some swear at them, unlike vg's, they are *relatively* cheap, and unlike vg's trying them on for size involves just a few minutes

.
The box stock answer to mods is always 'save your money and buy more gas'. But if you already have all the gas you need and are asking strictly about the mod in particular, I'd say there's probably not many out there that legally do anything to a flight characteristic at $200.00 so don't expect the difference to be miraculous , and you probably wont be too disappointed.
If in your avatar I saw a nimble CC 11 or PA 11, and had an inclination that your flying was purely fun and light I'd say you're probably not going to see much. But I don't, I see a belly podded top cub that probably gets loaded up with camping gear and flies heavy a fair amount
Two potential downsides;
If the gap in your surfaces is baggy, like say you have minimal fabric and paint, and also keep it polished, one may try and depart. If it completely leaves, all is well. If it partially leaves, it makes quite a racket banging around back there

. Some people add a dap of adhesive to the trailing edge of the stab.
The other potential downside is that they magnify things in both directions... In other words in heavy turbulence when the tail gets slammed by an air bump you will feel it more back at the stick.. This goes un noticed by most, and is not a big deal, but if you are one of those that gets the willies from turbulence, it is something to be aware of.
Take care, Rob
