Jet hammer Build

I got a Jet hammer (actually 2), and I was going to do something, but then I dunno which AMs would be good.
Mostly because I dunno if it will affect the hammer if they are too short.
Oh, and which LG are good for this too?

Always Red Squealer LG.

I use a Katana Max AM as the hammer arm. Then there's the K-Shield. I remember seeing a pic of asukuu's Jham build somewhere on this forum. He used a Beetlander AM.

katana max am.
dunno abt rt am but one that has -tec and gives moar free stats since tec will prolly zero out into the negatives.
