I was hoping adjusting the reach would make a difference, but apparently what I really wanted was 'free stroke' adjustment, which 105 levers don't have.
Reach will be lever distance from the bar when unloaded/sitting. Free-stroke is how far you can pull it back without engaging/pressurizing the hydraulics/master cylinder. I have no idea which one has which option until I look it up to confirm before set up and before bleeding (with free stroke adjustment capability sometimes with Shimano levers you have to run that adjustment all the way in or out before you bleed it or it won't bleed correctly.). I don't even remotely try and memorize it anymore.
