Having throw all 3 of these with similar layouts, here is my take on them:
The Attitude Shift and Special Agent cover the same amount of boards, however they do it in different ways. The Special Agent is more aggresive in the midlane and continuous in the backend, while the Attitude Shift is cleaner in the mids with a more pronounced arc/flip in the backend.
The Secret Agent is a different animal all together from these 2. It is much earlier than both balls with much less movement in the backend. This ball will have the most control in heavier oils, but it will look like the weakest of the 3 balls on most conditions.
Of all 3, I prefer the Special Agent. As a high rev player, it has more than enough movement for me in heavier oil, while also being aggressive in the backend on house conditions. I love it on Shark Pattern from inside angles. For me, the Attitude Shift is more like a super aggressive pearl, so I instead prefer a true pearl to fill that place my bag. The Secret Agent I keep for when conditions get spotty, as it blends out over/under nicely. However, it is usually too early for me to play straighter with, and it does not have enough kick to play inside angles.
