My opininion, for what its worth... Its a mindset that you are going to get it done! Technique is important but ive seen it done successfully with different styles, batter needs to be comfortable, balanced and KEEP IT SIMPLE!...I do like slight angle, bat out front , contact middle/top half of the ball, dont let a strike/close strike cross the plate- elbows and knees . slightly bent. When teaching this part of the game ...the strategy and reward of the bunt really needs to be made clear to the batter, trust me it will help! "Just my Opinion".
