450 Marlin,
I tried to respond to your e-mail yesterday and I couldn't get through for some reason or other. Here is my original response (although I don't think that it will be of much use now, I didn't want you to think that I didn't answer you).
Hi Roy,
It's a pleasure to be of service.
In the manual it states that the 66" Rogue should have a brace height of between 7" to 7 1/2".
I have a 30" draw with that bow so I shot it at the higher end of 7 5/16" for a long time and it seemed fine for me (with the arrows I was using at the time).
I started up my off season bow practices last week and I always use that bow to warm-up before going to my heavier bows. It's a really nice bow and I shot deer, black bears, and caribou with it, despite the relatively light poundage.
Have fun,
Ken
