It’s a good point, and our suggested pools are mostly in line with @guil-lambert’s argument. DAI/ETH (0.3%) and USDC/ETH (1%) are both stable/volatile pairs with non-overlapping fee switches, while still being in the top 11-20 pools by TVL. A solid candidate for a third pool to test might be ETH/USDT (0.05%) instead of our original WBTC/USDC suggestion. The key difference between these suggested pools and the ones @guil-lambert suggests is that our proposed pools rank much higher in TVL, which we think is important for simulating the outcome should new fee switch designs be implemented on more core pools. We do agree that having stable/volatile pairs and non-overlapping fee tiers is useful. --- _[View the full topic](https://gov.uniswap.org/t/fee-switch-design-space-next-steps/17132)._
