OS clutches are meant to be one of the better twin plates.... the HKS Twin plates are a pig to drive compared toe the OS ones.
It will be hard to drive compared to a stock clutch because it will be more on/off, you can still slip it. Its up to you, what kind of power will you be running in the near future?
If your only going to be running 150rwkw for a year or two, then its a bit of overkill/waste and you'd be better off selling it and buying something cheaper/easier to drive..
if your going to be running 300rwkw in the near future then keep it, it will come in good use and you'll learn how to drive it soon enough.
