You can twist or untwist the string you have to raise or lower the brace height, so long as you leave at least a few twists in it on the long side, and so long as it is not binding up on the short side.
I agree with the 2016 recommendation. I would try 125 grain points, and maybe 145 grain points as well, to see what shoots the best. The heavier the point weight, the quieter the bow, to a certain degree anyway.
