I will second what has been said on practice mastering the front brake's power. Likely you went over mainly because you weren't used to it yet.

One point that really helped me, is switching the front brake to the right hand lever. (I am right handed) So I can get the best possible dexterity when using it.



p.s. the 'brake modulator'; Avoid these products! It is true, they stop the problem of going over bars when using the front brake. But they accomplish this by disabling the brake! Basically they have a little spring hidden inside, so when you pull the brake lever you're really just squeezing the spring; not the brake pads.
