I was going to use ElectronCash, but I don't like the idea of exporting private keys from one wallet to another.
BCH is already bulkier than the bitcoin full node and they are bound to grow. Bitcoin has years of block-chains to load.
For just a trader/holder, I don't think running full node is a good idea.
Running a full node is the only way to run the real bitcoin, if you are letting someone else do the transaction validation for you, then you are not using the real bitcoin. I like to validate my own transactions and it's very easy to run a full Bitcoin Core node, just run it once a day for 10 minutes or so and you are synced.
And how is BCH bulkier? They may have 8mb max capacity, but their blockchain should be smaller, since they can't even fill 1MB blocks worth of transactions, but for some reason its so damn slow to sync.
