Need suggestions regarding handlebar grips

Can someone please suggest good handlebar grips for Scrambler 400x? I’m having a hard time in gripping the throttle since my hands are huge, my thumb easily gets to the fist join on my forefinger and I went on a recent 200km ride and by the end of it my hands were all worn out and blue.

Are barkbusters grips worth it? Or should I get grip puppies or something from Route95?
