It is a nice parts/figs set, very nice for an expansion, but kinda lame as stand alone.
I love the fact one soldier has a black helmet, Would have been better for variety to get one gray too, instead of two gray with neckguard.
I got half this set in a bulk of castle minifigs and loose parts. All men and weapons except for the saddle (a spare blue made the replacement), and only one simple feather/crest, plus the complete wall section, the four wheels and some little black parts.
I could easily build up the siege tower from parts found around on the net, except for the gate hinges and ladder, too expensive as spares.
Anyway I'll probably keep the set's men as-is to put in my mocs (as the ones from 6073, from the same bulk buy), and use/improve the wall section for my forthcoming castles (something like the 6080 or 6073 build up from parts).
And in the end, I'll buy one complete, when I'll find one less expensive than a BFF on e-Bay for example.
Jojo's arrangement is very nice, I must admit I love it, it is one "good" reason to want to get the classics.
