with good optics there isn't enough difference in light transmission between the 1" and 30mm tubes to wory about. The big thing about 30mm tubes is they have about 1.5 times the adjustment range. if your gonna dial your scope to shoot long range then you need 30 mm, if you'll only use it for a regular scope, or not dial past 600 or so then the 1" should serve you well.

You should check with Leupold on the construction of VXIII scope with the 30 mm tube. The reason I say this, is I had the 3-9 x 50 mm Euro model with the 30 mm tube and the internal part were the same as the 1" tube ( info I received from Leupold). They had made the 30 mm tube for European market and I"m not sure if this still applies on the internal parts. Personally I would get the 1" tube unless I was going to do long distance shooting...
Besides cost of a larger lenses, I don't see why 30mm isn't the standard. Its just better overall in alot of ways. That said, 90% of my scopes are 1". I buy and sell alot of used scopes, so 1" is what you usually see.
difference scope ?
