The wide distributions of low-pT vn's measured experimentally have proven that any medium background model used must not only render the mean value of the low-pT vn's but also the correct amount of fluctuations within a centrality class. In the study presented, we investigate if the eccentricity selection of the background medium within a given centrality class influences the high-pT v2. For this, we couple the BBMG pQCD jet-energy loss model with the event-by-event, viscous hydrodynamical model v-USPhydro and determine the high-pT v2 and v3 for three different e2-eccentricity selections of the background medium. We find that the high-pT v2 is directly proportional to the low-pT v2 and that the width of the low-pT v2 distribution influences the value of the high-pT v2 while the RAA is independent of the e2-eccentricity distribution of the background medium.
