DVE BD worth it?

[BStecke]

I already have a copy of Avia (SD, obviously) that I've used for my calibrations. Now that DVE is coming out with a calibration disc on BD, I'm wondering if it will provide me with much that my Avia disc already hasn't. I'm a novice as far as calibration goes . . . I don't mess with service menus or any of that stuff, I know to leave things alone that I know little about. So I'm going to be using the basic adjustments the set allows. Is this really going to offer me a vast improvement over Avia? I'm thinking it wouldn't really give me much except a click up or down here or there off of what I already have. Any input on this? I will eventually get an ISF calibration, but that's down the road, so the suggestion is already noted and penciled into the plans for sometime in the (hopefully) near future.
