One more thing I wanted to touch on here - obviously single asset depositing 115 ETH into this pool has quite a high slippage. The DAO is sensitive about trading due to tax issues.
My suggestion for simplicity of operation (we could split up these additions of liquidity in daily chunks but that would be way too much overhead) is that we create an LBP that converts 49/49/1/1 to 25/25/25/25 (BAL/GNO/DAI/ETH) and then add liquidity to the main existing pool without any price impact.
