Why anyone would want to use up bidding space on this holding is beyond me. Simply make a forcing bid......my p and I would bid 1 Spade (promising 4S's and waiting for p to further describe his/her hand); followed by another new suit (forcing).....I count asset points, so this hand is certainly worth 13+....
Being Vul, Id trust my p, bid 4H.......I can visualize p's hand w 5-6 small H w support for both minors albeit 4-3 w prob 1 S at the most.....prob 9-11 count
