      abstract     = {We revisit the rollercoaster cosmology based on multiple
                      stages of monodromy inflation. Working within the framework
                      of effective flux monodromy field theory, we include the
                      full range of strong coupling corrections to the inflaton
                      sector. We find that flattened potentials $V \sim \phi^p +
                      \ldots$ with $p \lesssim 1/2$, limited to $ N \lesssim 25 -
                      40$ efolds in the first stage of inflation, continue to fit
                      the CMB. They yield $0.96 \lesssim n_s \lesssim 0.97$, and
                      produce relic gravity waves with $0.006 \lesssim r \lesssim
                      0.035$, in full agreement with the most recent bounds from
                      BICEP/Keck. The nonlinear derivative corrections generated
                      by strong dynamics in EFT also lead to equilateral
                      non-Gaussianity $f_{NL}^{eq} \simeq {\cal O}(1) - {\cal
                      O}(10)$, close to the current observational bounds. Finally,
                      in multi-stage rollercoaster, an inflaton-hidden sector
                      $U(1)$ coupling can produce a tachyonic chiral vector
                      background, which converts rapidly into tensors during the
                      short interruption by matter domination. The produced
                      stochastic gravity waves are chiral, and so they may be
                      clearly identifiable by gravity wave instruments like LISA,
                      Big Bang Observatory, Einstein Telescope, NANOgrav or SKA,
                      depending on the precise model realization. We also point
                      out that the current attempts to resolve the $H_0$ tension
                      using early dark energy generically raise $n_s$. This may
                      significantly alter the impact of BICEP/Keck data on models
                      of inflation.},
