I have both the BW and I got a Threshold yesterday. It is my first D/T since a Maximum Risk a long time ago. I drilled it with a 4¼ pin to PAP and 4¼ cAp tp PAP, 70 degrees, pin under. On the fresh league conditions, on pro anvillane, the Threshold was way too much ball, even playing 25 out to 10-8 the ball would always check up early enough to leave a 4 pin. I had to spin the ball from deep to get enough length not to go Beak. It's a great heavy rolling ball and even on this hooking house shot had zero rollout, even though it was clear the ball was burning up - it was still continuous and hit the pins with a very loud sound and good action. The Black Widow (Polished, 4x4 75 degree, Pin High) on the same shot was about 5 feet longer and fairly angular. This ball also was too much after I switched from the Threshold, I would get better length but the ball seemed to go sideways and always go a little high. The ball that worked best on this shot was a Vibe. So I would drill the Threshold, sounds like you have enough oil out there for it to work great cause the ball neeeds oil.
