Do you guys feel these are necessary in your set-ups? So far I have had LimbSavers on all of my bows and have yet to purchase a set for the Bengal. Debating doing so in general, but in between the BowJax and the LS Ultra Quads. Not that I'm obsessed with speed, but I have read that they will rob you a little and if you aren't having much vibration/noise then they wouldn't really be necessary, no? Just wondering what everyone thinks.
