I just mounted a 2-7x33 Leupold on my Omega and I used medium Weaver rings. The main reason was I had an extra set laying around, so I mounted them and they work great. You can probably get by with low but you may have to remove the rear sight, especially if you use flip open scope caps. I agree to stay away from see through mounts. I used to use them and prefer the regular mounts much better. None of the gunsmiths I know like see through mounts.
