I think this hand is not good for 2♠ that required a monocolor weak with only a bidding , for barrage because has a second suit of 5 cards , instead is in minimum force (14-16) and in system that i use (Stayman) not 6-5 but 5-5 spade-club is managed bidding 1♣ for bidding 1♠ in second round and inserting plastic valutation of the hand (+/- 1 point , +/1 a card) to treate like a 5-5.
