I grew up in props and we always planned on V1 max and in most cases V1=Vr. It certainly was easier to abort a prop plane over a jet. Much more controllability on the runway and easy to abort. It was a big learning curve making the transition to jets and taking them airborne at V1 is the way to go. Our FMS has a V1 max function but our SOP calls for balanced field or V1 min. Ask to try a V1 max in the sim and I think you'll find that flying is the way to go. Good luck
