I put the sims cable module on my vulcan, I didn't notice any benefit besides looking cool, On my trykon I had a little bit of string buzz after the shot so i put some cat whiskers above and below my string shox and it killed the buzz and ate 12 fps off of my speed, we pulled them out and they weighed 69 grs. Then we pulled out the stringshoxs and it didn't any difference.I have put them both back in recently to keep the buzz down, there seems to always be a sacrafice with bows nowdays.
