I used to use a regular rest for years, then went to a drop away for a few years and now have been using a WB for the last3 years with no problems at all. Never noticed any difference in noise but then again I never did any scientific DB readings, Im basing my analasys off the deers reactions to every shot before using a WB and after I switched.I tell you one things its nice to know your arrow will be in place after drawing, while moving into position to make a shot.
