Pools/Options for Mining ETH / Converting to RVN in HiveOS

Several discussions recently about people mining ETH and then converting to RVN, which makes economical sense because of ETH's recent price.

I've seen 3 options: Unmineable; Prohashing; and MiningPoolHub.

I'm a HiveOS user, and I'm currently trying out Unmineable, but the conversion rate seems very low for what I would otherwise be mining directly. Has anyone had luck utilizing the other two pools for this process? Their websites offer no support for how to integrate with HiveOS.
