Took my recently acquired Win & Win/Dryad ILF longbow out to the range today to play around with some different arrow combinations. The bow is #48@28 and really likes 45# spine wood arrows with 145gr points. The only problem is that it is very noisy. Or at least it seemed very noisy when I picked it up after shooting a 3D round with my deathly silent Bob Lee Blackhawk. Not having any real experience with ILF bows, are they just a bit noisier than other types of traditional bows? Running a brace height of 7 1/8". Too low? Do I just need to add some string silencers? Or is there something funky going on with the tiller? It groups well with 500 and 600 carbons also so I don't want to screw it up, just make it quieter.

Glad it worked.
The ting is that you didn't describe what the noise is you are hearing. Is it noise in the string, the arrow shelf/arrow rest area, around the limb butts, where is the noise? Every type has a different cause and a different cure.
To be honest, with a past center ILF riser and the draw weight that you stated I would THINK that the arrow combination is weak unless you have the sideplate built out well past center.
Tiller is waaaaayyyy over rated, but in ILF you can use the bolts to adjust it, which effectively does the same thing as adjusting the nock point.
The brace height could be too low because in my personal experience lots of longbow limbs are "noodley" on ILF risers that aren't specifically designed for longbow limbs. and you have to increase brace height to take out the excess "noodling" and limb vibration.
Just a thought.
Silencers will help alot. I find fast flight strings very noisy in general.
You can put alittle mole skin under limbs and limb savers will help alittle but a good puff ball silencer helps
No idea onBH, but totally agree with D, most are noisy. I would throw a pair of wooly whispers on the string, and 2 pair of mini limbsavers on the limbs. ‘Never gonna be as quiet as your Bob Lee
I think you should be at 7.5 to 8”, but I find all ILF’s to be a little noisy.
