RE: bow noise
Look up your axle to axle length and brace height for that bow. Then get out your tape measure and check them. If the axle to axle length is more than 3/4" longer than it's supposed to be, or the brace height less than 1/2" shorter than spec, your string/cables need to be readjusted so the they will be under the proper amount of tension. If they're loose and floppy, the bow will make a lot more noise than it's supposed to.
THEN you can look at getting a string suppressor, if it's needed. Otherwise you've just slapped a bandaid on the problem and not fixed it.
