ping K15 hooks to slices

[andy cap]

Hi does anyone else use Pings K15, after 1 year of buying the clubs ive started to see a pattern in the ball flight,

pw, stright

8,9 iron draw

7,6 iron 10 yard draw

5 iron 15 yard draw

4 an3 hybrid slight fade

Ive been to to pro instructors both have said my swing and grip are good, but if i dont feel like my follow through is over exadurated i hook or draw the ball, ive seen other posts on here that have said that heavy offset clubs cause hooks has anyone else had this problem with the K15 irons

ps i hit my K15 3,5 woods and my K15 driver with a slight fade or straight
