Thickness of Voltric 70 frame vs Armortec 900s

VT70 is in the middle flanked by AT900T and AT900P
I just realised that the thickness of the frame of voltric 70 is reduced compared to Armortec 900 T/P.

The lateral part of the frame is generally thinner with the exception of the 'bulge' at the Tri-Voltage system.

The VT70 has the same thickness of the frame as AT900 at the Tri-Voltage system 'bulge' area, whereas, the tapered frame is thinner than AT900s.

I supposed this reduces the air drag and hence improved upon the Armortec series.

I guess, that's good news for folks who like head heavy balance racquet with reduce air drag.
