I have heard that Sims string leeches rob you of arrrow speed more than they dampen your string vibration/noise. Is this true? How bad do they effect arrow speed? What is the ideal setup for a blend of effectivness of string quieting while maintaining arrow speed?

Anything you put on your string will steal speed from your set-up. Leeches are some of best at maintaining speed and decent noise reduction.

Good Luck!

I would have to agree with Cloud 9's post. I've tested my setup a couple of times and found I only lose 1 fps with my leeches on the string. With the lack of string noise on my Patriot....it's a 'nobrainer' with my setup.

Depends on where you put them on the string, just like any other silencer. I didn't lose anything when I used them. I just didn't like them because they didn't last long enough, and any rubber silencer I have used made a rubber whipping kind of noise. Still quiet mind you, but the yarn puff balls don't even do that. Not to mention they are cheaper and last a lot longer.

where you place them on the string?
is there a certain spot on the string that keeps you from losing fps?

go to sims site it will tell u where to install them and how u install them. they do work though

The closer you get to the center of the string with any weight the more speed you lose. However there is usually a sweet spot that will actually gain you a few fps. That is why most new bows come with speed nock sets on them. With a single cam it will be on the bottom, normally a few inches up from the cam. On a dual cam bow you would most likely need to place them on the top and the bottom.

You would need a good chrono to find the right place to put them.

So the closer to the axle's you place your dampners the less speed you would lose. You just need to experiment to see where they are the most effective at reducing noise and vibration. I haven't seen many string silencers that cost you a large amount of speed though. Not enought that I would consider not using them. The less vibration in the bow the better. I even use them for target shooting. Why have my string vibrate more then it needs to.
