I own 4 bows , their brace height is between 6 5/8" and 7 1/2 " , all have fallaway rests on them . That should tell you how I feel about that type of rest . I curantly have a bow on order that has an 8" brace height . As to single cams and nock travel , Im not jumping into the fire here , I will tell you I dont curantly own a single cam bow and never intend to purchace another . I did own a patriot single cam a couple years ago and it was a fine bow .
