FFF,
If you were to follow the departing aircraft onto the runway you would not be able to commence your take-off roll immediately and there would be a delay. This delay is going to be similar to the delay at the hold bars, therefor no need to creep IMHO. I would let the person in front start to roll and then take up my position. This saves the nose taking a sandblasting.
How is commercial life treating you? I followed your CPL diary and have now found myself in similar shoes to you with CTC.
Hope all is well
The Reverand
