I'd give a thumb's up to TWOHAND834's advice.
I've never thrown a 920A but own Reign and goes long and comes off the spot hard.
For reference I also throw 17-17.5 mph at the pins and have 275-300 rpm's - which makes me slightly speed dominate. My Reign is drilled pin over ring 4.5 x 4 stacked with no x-hole - sorry I don't know the angles, I'd guess 45 x 4.5 x
. We left the hole out on purpose to see if I needed one to help with the reaction, but for me it works great without the hole. It's always easier to add the hole later, assuming you don't have to add one after drilling.
I can play it straighter on fresh shots and it opens up the lanes as the shot breaks down. It always seems to get easy length but because it's so strong on the back end it definitely lets you know when it should be put away.
