I just got back from seeing EP7 again, and I'm going to make a bold statement.
The Hero, non-bladed, Screen-Used Lightsaber has grips that are short. There is a 1/8 or less space between the grip and the bottom, and 1/8 or less space between the grip and the clamp. The grips on the EP7 Lightsaber are shorter than the ESB Lightsaber.
You can write that down, save it for April when the Blu-Ray is released, and see that what I've just said is true.
In Maz's box, when Finn is handed the saber by Maz, in the snow, when Rey is bringing the saber up to ignite it, and at the end when Rey is holding the saber out to Luke. In all those shots, the saber grips are 1/8 short of the clamp.
Exactly like the VD.
The Maz box scene is interesting because of how it plays out.
Rey opens the box, but you don't see inside.
Cut to Rey's face.
Cut back to the box and see the saber, but the angle is bad to tell the grip length
Cut back to Rey's face
When it cuts back to Rey reaching in the box to touch the saber, you can clearly see the gap.
At the end, you get basically a side-shot in daylight when Rey first extends the saber and the gap is there.
If you don't believe me, no worries, I'll see you guys in April with the ably-Ray. But if you're making an EP7 Lightsaber and you want it to be accurate. you need to cut grips 1/8 short at the top and the bottom.
Of course, It's not like I am some sort of authority on the issue so I cannot expect everyone to just take my word for it.
