i hear the bengal is already one of martins quietest and vibration free bows, you may not need them. i would shoot it without it first and see what you think. being that you already have owned limbsavers before, you will know if you think you need them or not.
I try and find a happy medium with my hunting bow. I shoot a 385 grain arrow and do what I feel needs to be done to quiet the bow. I like knowing that I can pretty much shoot one pin out to 30 yards. One thing I do want to add about string dampeners......when I do use them Im really like monkey tails, they go on easy and they dont effect peep rotation.......................plus they really do work well!
Went with BowJax on the limbs this time since the Bengal came with Bowjax on the strings. I like to match and I believe they work just as well as the limbsaver versions. They do take a bit more space on the limb however, not a big deal in my mind.
In comparison, Hoyt CRX shooting noise with similar string dampeners was 80,5 dB. But Hoyt also has factory installed limb dampeners. I installed the limb dampeners to Onza 3 later, but did no longer have the dB meter available. I would assume Onza 3 would get closer to CRX readings with the limb dampeners.
Arrow speed was 267 fps before and after Slipjax installation.
