Sumo - yes, I have experience with them. The Classic has a few notable changes:

1) Side folding stock
2) Redesigned lower receiver

The diopter sights are available on either the Classic or the ER models....and they SUCK.

The side folding stocks have a reputation of self destructing (the plastic is cheap; and the clip that holds the stock to the front handguard has a tendency to pull out and stick to the handguard).

The lower looks like butt, but is lighter and has "better ergos" (the mag release is easier to reach by those with short fingers). However, you forfeit reinforcing.

I selected the "ER" model because I planned on installing AR type sights anyway (cross training simplified). The M4 style stock has too many options available to not appreciate, but you'll want to replace the factory "receiver extension" with a milspec aluminum one.
