The only down side to the BLD is when you are trying to get up a slippery hill. As several people have found, excessive BLD action locks out the brake pedal, so if you realise you aren't going to get up when you are half way & try to put your foot on the brake to just stop...
That is when a couple of people have found themselves rolling back downhill with a brake pedal that feels like it has a brick under it and no brakes at all.
Just something you need to be aware of though, (hopefully) not a regular occurrence.
