  He has designed an attacking d4 repertoire built around establishing a big pawn centre (c4, e4), forcing moves, and gambits.

  I feel that the most ambitious, principled and aggressive 1.d4 repertoire is the one given by John Cox in his book "Starting Out: 1.d4!". Of course these are the most ambitious lines for white in chess so they have also got extreme amounts of published theory and as they lead to very sharp positions, not knowing the theory may lead to quick losses for white.
