I flew my Eagle with 69 points of shields, so the Viper's shields were plenty - shields are only needed when they hit you, and in a small ship you are not the highest threat until you open fire - at which point you should not be in their line of fire for more than a few seconds every now and then. If your shield does drop, silent running + boost is your friend, shake any unwanted attention, circle around, and come back to finish them. I do have more now in the Eagle, thanks to Guardian Shield Boosters.Viper 3 shields are paperweights. Not sure how you would call them tough.
But the Viper 3 has a lot of armor if you want it to, so losing shields from time to time is no reason to leave. With the eagle I bail below 40% hull, the viper was fine until 20% - usually thrusters are most at risk when I mess up some missile evasion or overstay my welcome when under fire.
