Tony,

If your only using the central section of the field of view your better off with a 30mm plossl like the Celestron Ultima, which will give a tack sharp view right across it's 52 deg FOV.

There is no point having an 82 deg AFOV eyepiece, when you can only use 1/2 the FOV anyway. In terms of "on axis" performance a good 30mm plossl will walk all over that 30mm 1rpd for similar money.
