I never traded long-dated options when I was in finance, but anything with longer than a three-month maturity was crazy expensive in terms of the spread you'd pay. These are not liquid instruments.
It's been a while since I've done the maths, but I'm pretty sure it'd be cheaper to buy shorter dated puts and roll them over on expiry. Which would still be very expensive.
