Seeing as i cant find any second hand fixed bridge ibbys to purchase for my first 7, i thought i would ask some questions, and for your opinions on these new models.
My little experience: I Have played or owned both RG Prestiges and RGD's, but never in a 7 string config, and have enjoyed them both.
1. What kind of difference is going to come with the scale length. 25.5 vs 26.5?
2. Is the Tight-End bridge significantly better than the Gibralter Standard II?
3. Is the BKP pickups, ebony fretboard, and Gotoh Magnum Lock tuners worth the extra $500 in the RGD7UC vs the RGD2127FX?
I prefer the simple setup of the RGD, 3 way switch and one volume knob.
I do not own an RGD yet, and would like to.
The RG752 is much more price friendly, especially since i am going to swap the pickups out.
I think i would be playing in either B standard or Drop A. The extended scale of the RGD would help with Standard A or Drop G, but would be hard to get a comfortable B standard tuning i think.

Well, you did a good job picking out some guitars.
That's a toughie. They all have some great features. I can't really pick one out, because I'd take features from all of them and combine or swap them around.
The Gibralter looks slightly more comfortable, but I don't have any experience with it. I also wouldn't let the deal breaker be pickups, because that's the easiest remedy out there.
Ebony is my favorite neck wood, though, so the RGD7UC has that going for it. The scale length is going to come down to personal preference; I'd say if you don't have years and years behind a 25.5" 7-string, you'll be fine. I don't really care for longer scale lengths, though, but I don't think you'd have much of a problem in standard B or drop A with it.
