Wow! That's way too low, don't shoot it like that! I'd want to be in 7" to 7.5" brace height range to start with. Some guys shoot those around 8", but I'd work towards that slowly as you get settled in with it.
Length sounds right for a 62" AMO, I'd start twisting it up til you hit the brace height, or hit 4-5 twists per inch. If the strings starts coiling back up on itself when you twist it, you've hit the limit.
If it won't brace with that string I'd call up Oliver Stacy or SBD (Silent But Deadly) and tell them your situation. Either of them could set you up with what you need. They could probably figure out if that Damon is FF ready or not.
