Bikes: too many of all kinds
Do you have any specific concerns in mind you would like to share with us?
If the frame has rack mounts, it is no problem to carry racks, that is what the bike is designed for. Obviously the short chain stay track bikes do not have rack mounts (or any mounts if they are truely a track bike).
I commute with FG and panniers, although that bike has more road geometry. Accelerating and braking are slower when carrying weight on the rack (its is significantly faster even comparing wearing weight on my back vs carrying the same weight on the bike).
Do you have brakes? If you are carrying significant weight, you will need brakes. Obviously skid-stops don't work too well with 20+ lbs on the rear wheel. The extra braking power of brakes is important here.
Personally I use a messanger bag most of the time. Backpacks have the weight too high, and generate too much sweat. Panniers slow the bike down, change the bike's handling, and have wind resistance which is horrible riding against the wind. Messanger bag (with detatchable front cross strap) work best for me, but obviously I can carry more weight with panniers.
