I think shortening the PoW is still highly desirable. (E.g. Stop PoW once we hit 128)
Cutting it this short doesn't impact the PoW coin supply greatly anyways. (Only about 2 million)
But this will guarantee that multipool cannot affect the market. New investors want this also.
Reason why supercoin isn't getting as much attention as it should is due to both extended PoW and very high PoS rate.
If we want this coin to get more attention, it seems the only way to really shorten & reduce both right down.
This is just what I feel right now based on the current altcoin market trend.
