If you just want an eyepiece to find things quickly then I wouldn't recommend any "superwidefield" eyepiece in the 80 degree range. You will have to 'look around' to take it all in which is not what you want it for. Something in the 50-60 degree range will be more suitable.
What you are really interested in is TFOV (True field of View) which is the total amount of sky you will see.
