TAD packs are great. They are not for sale at the moment, but this year's lineup should be hitting one of these Fridays. However, the FAST line is on hold this year, and they are releasing the CORE line of packs. They only posted one picture of a prototype, and then pulled it for fear of knockoffs hitting the market before they could perfect it.
It is not your typical PALS pack. The SDS Tac Bag is the closest thing I have seen to the set up they had on the prototype. I will not describe it any further, per their wishes.
Given the history of TAD packs, the prices will probably be a little lower than Kifaru, but they aren't custom made to fit you.
I would also like to add that there is a reason most smaller packs do not have the suspension of larger packs. Weight. All that padding adds pounds to the pack, and isn't going to make it any more comfortable to carry what weight you can pack in the smaller bag.
