basicly you want them fairly far out onto the ends of the limbs, but in far enought that they do not get hit by the string. On this particular design the tips are where the majority of vibration comes from, so that is where I wanted to add some dampening. An Excal flexes along its entire length and in effect you are more adding mass than dampening the tip so IMO a bit further down the limb would probably produce better results. The limbsavers I used were recurve ones for a trad bow. The Excal is a wider limb so you could use larger ones and possibly make more of a diferance. Be aware though that adding mass to the limbs does reduce vibration, but makes it slower, so you will loose some arrow speed. How much will vary not only on where you place the saver, but what size it is. A few feet per second is more than acceptable in exchange for more stability IMO. Which style is more of a personal preferance....if they are the same mass, shape will only play a very small part in how it works.
