Are you using the latest 11speed shimano shifters? If so, i understand that the pull ratio is different with the newest 11 speed gear.
If not, I’ve used the same brakes on 10 speed 105 and they’ve been fine. Only ever used a barrel adjustable noodle when i had really fat tyres fitted, the point there was that i could remove the wheel without tools.
For best bite, power and feeling in your brakes, Mini V’s will need to be set fairly close to the rim. Use the brake block adjustment spacers (fat one in the inside) if you’re running a typical narrow road rim. The easiest way to tell, is to hold the brake arms in against the rim. The arms themselves still need to be 90 degree or greater from the rim for the best performance. If they are beneath that angle (closer to the tyre) then you’ll be looking at to much cable pull, which typically will result in squishy breaking.
Post some photos if you’re still stuck.
TIPS – make sure your outer cable is not to long.
+ Tension the spring screws a reasonable amount, will make the responsiveness far more snappy.
