Rod,

It is entirely possible that you went from a relatively average weight aluminum arrow to an extremely light ICS carbon. A change of 200 grains or more is definitely possible and a 200 grain difference or even slightly less is going to result in a definite change in feel because of the lack of mass weight to absorb the energy of the bow.

...and even though you lowered the draw weight when you backed the limb bolts out you also made the bow slightly less efficient because of not having the limbs bottomed. This can increase noise and vibration to some extent though it varies from bow to bow and setup to setup.

You also mentioned changing your string/cables. Is it possible that a different type of string material or even a different brand? "No-creep" or "low-creep" strings (Winner's Choice for example) can be much harder on a bow than some of the factory strings because of the lack of give.

On the other hand it is also possible that there is something else wrong with your bow now...ie, cams out of synch if it is a dual cam bow...or cam out of timing if it is a single cam bow, which may lead to the same type of situation. But, if the difference was only noticeable after you switched arrows then it would seem relatively simple to identify the arrows as the problem.


I am not a big fan of the Whisker Biscuit so I can't really help you out in that department. I admire its simplicity but feel that there is just too much contact between rest and arrow. I do know that some folks have trimmed the riser-side of the bristles to reduce fletching wear.

Hope this helps.
