Given near-term constraints on the sETH-wETH pool, the next pool we should look to add towards our goal of leveraging Synths is one containing sBTC.
These are the two pools I believe we should consider:
sBTC-wBTC: More efficient sBTC pool than competitors, can effectively own this swap; Satisfies sBTC requirement
sBTC-wBTC-renBTC: renBTC would add a larger addressable market to the swap; Satisfies sBTC requirement
The main argument against a BTC pool is to keep rewards high for stable LPs
