If for example, Vs was 100 Kt, V2 would be 120 Kt, and Vref 130 Kt, so 10 Kt below Vref is totally survivable.
I won't presume to debate the techniques, but one caveat on the comment comparing Vref-10 to V2: For the takeoff case your engines are already running at the power you want - if you've ended up well below Vref, there's probably a good chance that your engines have been brought to idle, or close to it. As a consequence, the engine response will be rather sluggish on many jets, especially turbofans.
As a result, if you fly the balked landing like a takeoff, you're going to be very short on energy.
This accident in Fredericton contains some of those elements. (Section 1.18.1.4 discusses the go-around/balked landing specifically)
