Since you just got your first reactive (and a Widow is a great ball). I think you need work it and on a proper release, if your not getting performance out of the Widow.
In just what way is it not performing now? not hooking? And what do you mean by "throw a fingertip perfectly"? Are you cupping your wrist? to change the roll? and/or cocking it to change the spin?
You don't need to go to a totally different release to make it perform.
Here's some info on the Two Handed delivery.
