I will be getting an 09 GT-500 this afternoon to compliment my XXL and I was wondering if it is worth it to swap to the newer REV cams on it (GT-500)? What are the benefits to this? If I remember correctly, weren't the older cams a little faster than the new ones? Also were the older cams draw lengths right on or were they a little long? I am probably about a 28.5" draw and this bow is a 28" but I got a good deal on it so I will deal with the draw length later. Thanks.
