I disagree with the above two opinions. Carry the volume that you would normally carry in rear panniers in the BOB. Don't bring extra just because you can. Use front panniers to balance the load fore and aft on the bike just as you would if using rear panniers. All the weight in the back is an *** load. Front panniers also make for easy access to items you need during the day such as weather gear and snacks. And yes, the bike handles fine with just the front bags alone. You can eliminate the high and heavy handlebar bag...
