The L51+ bottleneck, if you will, could be due to the Yersinia pestis outbreak that caused the downfall of the Neolithic farming communities across Europe (including non agriculturalists like R1b). I don't see why it has anything to do with France, in fact, the data has shown L51+ is well distributed across Europe and isn't linked to any specific region. L11+/P312+/U106+ would all be post-plague and in north-central Europe.
Are we sure Y-R1b-L51 knew a bottelneck phenomenon? What we a re sure is that it knew a founder effect, what doesn't everytime imply a previous bottelneck: only mutation a some stage (of L23 lineage here)... And some new discoveries in the northern southbaltic plain of Europe could provide us surprises.
I agree with you at a global level (the "bottleneck" theory isn't yours seemingly; I have to date no opinion about its reality); Concerning Balkans for L51 I'm not sure, maybe rather NW Ukraine not too far from N-E Carpathians? only a bet for the game.
