I had a post up earlier and mentioned reworking the grip on a 70's Browning explorer 2. I was also thinking about lowering the shelf by about 3/8" to 1/2" to put the arrow closer to my hand. I have seen this done on other bows mostly older Bears. How much do you think this will affect this bows tiller? I do know that every one that I have seen have come with an elevated rest from the factory,and I am shooting this one off the self already. Thanks Joe.
