Chopjock,
To reiterate what Double Bogey is saying - you seem to be hung up on the idea that getting VTOSS will somehow protect you from TR failure, and that being under this speed is somehow "exposure".
The reality is you are ALWAYS "exposed" to TR failure - you just may be better positioned if you are say above 1000' AGL with 100 kts airspeed and a clear area in front of you. Anything else, and its not going to be your day.
