For those that have both recurve and longbow do you find one being quieter than the other with three under? The reason  I ask is because I only have longbows and the extra noise from the bow seems to be the twang of the string. If that being the case would the felt pads on the recurve limb tips be better at stopping the twang than  the longbow with beaver fur? Thinking of purchasing a recurve.

If I shoot with tension in either of my hands 3 under the shot will be loud, and the recurves will be the loudest.

If both of my hands are relaxed and I draw the bow with my elbow (back muscles), the shot will be quiet with either. It will always be quietest with the longbow.

The felt pads on the recurve limb tips are to reduce the noise from string slap.  I don't think they do much to reduce twang.  You shouldn't have string slap on a longbow, because there shouldn't be any contact between the string and the limbs, except at the nocks.

I recently bought a Hoyt Satori recurve that came with limb tip pads.  I didn't put them on at first, until I got tired of the noise.  They didn't help with the noise much, which was mainly twang.  I replaced the stupid plastic bumblebee thingies on the string with real string silencers and it made a noticeable difference in the sound.  Not quiet, but probably as quiet as I'm going to get it.

I haven't noticed much difference in noise shooting longbows and recurves 3 under vs split. Longbows are generally quieter than recurves, whether shot 3 under or split.  3 under is generally noisier than split, whatever the bow may be.
