Quietest of all was a 66" ILF setup running 46@28 consisting of a 21" Black Bear WARF riser and size long Sebastien Flute Elite Plus limbs and a Hoyt Super Rest. Even at 7.25" it was nearly longbow quiet and blew my mind.
Far as dedicated hunting recurves, another super quiet recurve was the 54" Shrew Lil Favorite (=Java Man Helms Deep) that I just sold to fund my new Silvertip Carbon, which is also among the quietest recurves I have ever shot. Also the Toelke SS 64" and Caribow Tuktu EX. Both just a measure quieter than a regular 'Tip which is quiet to begin with. The RER XR also comes to mind. As well as the Robertson Fatal Styk. The Fatal Styk and 'Tip Carbon are both comparable. Morrison metal ILF riser with Dryad Epic limbs was also very quiet for a recurve.
If I had to rank a couple I'd make it:
1. BB WARF / SF Elite Plus combo
2. Shrew Lil Favorite (=Java Man Helms Deep), Toelke SS
3. Silvertip Carbon, Robertson Fatal Styk, RER XR, Caribow Tuktu EX
4. Standard Silvertip, Hoots Lil Hoot, Toelke Lynx
5. Morrison metal ILF riser and Dryad Epic limbs
6. Border Hex limbs
I have shot others but these come to mind right off the top of my head, as the quietest. The ranking needs to be looked at as not a huge spread from 2. to 3. to 4. but noticeable differences existed and the jump from 2. to 4. is pretty decent. 1. was kinda in a class of its own. 5. and 6. another step
from 4. All are very quiet in general.
As you can see, statics tend to be quieter than working recurves. The working recurves that have shined based on the list above are the SF Elite+ combo (amazing!) and the Silvertip Carbon and Robertson.
Nearly all on the list were tested with either LRU 12 strand Rhino strings or 8-10 strand D10 or 12 strand D97 and generally cat whiskers though a few had wool puffs. I have found that silencers and skinny strings just make an already quiet bow quieter. If it is noisy to begin with they will only dull it down some. Heavy arrows help but if its not pretty quiet at 9-10gpp its almost kinda like what's the point. Oh btw I don't generally use wool wraps on my string ends either.
The only bow I mentioned that had wool wraps on the string far as I remember was the RER XR and they came on the string.
