Swordsmen should never have sword and buckler. They are MUCH better of with two swords or sword and dagger.
Why give your youngbloods bows when both your champions and your swordsmen shoot better?
Why only buy pistols in braces? With 6" ranges, you'd almost never get to use them both before enemies charge at you. Giving one to each Champion seems like a sounder plan.
Duelling pistols are ace, why not have some for everyone? Hitting on 3+/2+ is awesome.
Oh and Blunderbusses are nice, when playing Marienburgers I love getting one or two on my marksmen so a youngblood can get grab one with his first skill increase, that item gives loads of experience in a very short time.
But yeah, apart from those things that is a very all round list that can both affect some damage at range, and in melee. To me, being effective at all ranges is better than just being specialized in one thing.
I personally find the Kislevites as rather weak, combination of all the human warbands, with a rather weak big guy thrown in. Yeah I said it, the bear isn't that strong, a volley of crossbows and he's down to one wound and a liability. One more and he can easily hit the deck. They do however have henchmen that have +1BS with handguns, sort of bad Reiklanders (which is meaningless unless you play with some rules to make handguns viable, such as the +1 strength for them), +25gc in an ancestral Item, and a S4 hero makes them seem like a combination of Middenheimers, Marienburgers and Reiklanders.
The averlanders however are crazy good. First their good heroes are specialised on either close combat or range, and while I think it is bad to specialise your warband in one field, having individual specialists is essential. Bergjaegers can set traps, which many people forget, but once they start to think about it. It is crazy good. Just hide somewhere, place a trap whenever you can't shoot, and your Bergjaeger is basically unchargeable, if they decide to charge him, they'll set off loads of traps and suffer plenty of S4 hits, meaning one Bergjaeger can easily screen an entire part of the table in a matter of turns. With their good BS they are also excellent heroes to give Weapons Expert so they can use a bit of different weapons to make holes in their enemies. Also note that while Bergjaegers are three advances ahead of youngbloods, they only start with 4 more experience, meaning they will grow even better over time. Oh, and did I mention, they can start with hunting arrows?
Along with them you can get Halflings, who with a bow costs 30gc, and that is the cheapest BS4 archer you can get. They can easily get to BS5 making them dead-eye shots. Sure, they don't have a lot of T and S, but you have a pretty decent warband for that among your mountain guards, the champion and the leader. Also, the only reason to take a Marksman is to get a Blunderbuss, which is pretty useful, due to reasons discussed earlier, I like taking Weapons Expert with a Bergjaegers first advance and then stick him with a Blunderbuss and a Crossbow. But the Mountainguard have all the good items from his list (bow, Crossbow and Pistols), but better close combat options, and more armour available.
To me, the Averlanders are probably the most well rounded human warband. Every choice they have is pretty sound, and there is a reason to take a variety of equipment. I love those Averlanders almost as much as the Miragleans.
