I'm just starting down the 14.1 road myself and have a LOT to learn. That being said, my break speed is almost always determined by how hard I have to hit it to leave the cue ball where I want it (usually the middle of the table). I too am somewhat "old school" and tend to go for the softer breaks if there is a choice. It's safer for me at this level as the last thing I want to do is scatter the rack if I miss the break shot
. If I don't have an opponent, I'll hit them a little heavier though.
Cheers,
