The Black Wolf makes for a sweet rig. I had one rigged up with Max 5's, man what a bow, absurdly powerful smooth and fast. I also used Uukha EX1's on it and preferred that setup because it was more mild mannered and "sweet" with equally smooth action. I got rid of it because I got preoccupied with super tuning it haha. Made it too easy. The Wolf is radically deflexed but they made the pocket angle such that its same adjustment as many 25" riser
You should have a range of about 5# depending on how far you turn the bolts in and out and about 8# over marked like you said. With shorts like youre talking about also keep in mind your draw force curve will peak quicker, for 27" you should be just fine Id try bolts bout midway.
