I think 30x is a too high magnification to start out with. I even sometimes find the 25x on the old eyepiece slightly too much, although that's also partly to blaim on the fov, I think. Might in time try the WA 30-60x to see how that is.
I too prefer a lower starting magnification. I like wider fov and especially greater dof.
You may like the Nikon EDG scopes. The zooms start at 16x or 20x (their fov is not wide by todays standards but it is acceptable) and there is a big selection of fixed mags available.
The view is fantastic. The 65mm with the 24x fixed is lovely. And with 16x fixed the view is sooooo wide and bright.
The down side is their weight. But the 65mm is ok for me to carry all day.
