A straight/flat/riser bar requires flat-bar/MTB brake levers. Make sure they are compatible with cantilever and caliper brakes; NOT V-brakes, which have a different cable pull.
Pursuit or bullhorn bars work best with Tri or TT brake levers, which are inserted into the ends. These levers do not work as well in DIY flop-n-chop road bars because, as you mentioned, they lack the straight section at the end.
Moustache bars work best with traditional road brake levers mounted at the curves--the ones you already have should work. There are also mustache-like bars made by Nitto that are meant to be ridden primarily on the ends and take MTB levers there.
