1NT = 15-17
Feel free to use whatever system you want but at the table we were playing Woolsey. (2♦ = 1 major 2♥ = hearts and a minor). Double ostensibly shows a major-minor 2-suiter with a longer minor but I guess I'm not sure if it can be used to show big hands like this.
Anyway, what do you think best strategy is here?

(1NT)-?
