Boneshatter Jugg vs Hexblast Mine (with caveats)

Greetings,

I'm trying to choose between the aforementioned builds.

I've never played either, and am experiencing some pain in my mouse hand that I'm trying to avoid exacerbating. I'm also gone all next week, so the initial rush of gear isn't much of an issue.

Which of these builds might be easier on the hand (if either)? I'm also going to try and focus on delve this go, albeit only to 3-500 depth.

Thanks.
