tbyrd,

If you like the Guardian, by all means, buy it. However, if you like the Allegiance, go for it. The MeanV system is made by a guy on Archerytalk. Just do a search for MeanV2 and you'll get the info you need. He's a great guy and makes a very nice product.I like it much better in terms of visual appearance than the standard STS system.

Of course, placing a quality stabilizer like a Simms modular or Stealth will also help any bow tremendously. Also, the Stealth String Leaches should replace the factory ones. They really do a nice job as well.

My Allegiance setup in this manner is amazingly quiet and shock free.
