Just my 2 cents but that 10 pt. looks like it'd be right around that 3 1/2 range, with about:
15 inch main beams
16 inches of mass on each side (MAYBE)
16 inch spread (Again maybe, hard to tell from one picture)
2.5 inch brows
5 inch G2's
4 inch G3's
2inch G4's
= 107 inches <- My guess (Very roughly)

That 8 pt may be 2 1/2 and lucky to break 90 inches.

Just my opinion.

The picture that I attached was one that I managed to get during bow season and it BARELY broke 130.
