For my next build I am considering one of the following actions. Chassis will be a KRG W3 (Gen 6):

Lone Peak Fuzion
Impact 737
Zermatt TL3
Terminus Zeus
GAP Tempest

If any of these actions require me to make modifications to the KRG backbone for either the trigger hanger or anything else, then I will remove it from the list. If you have experience with either of these, please let me know. I already have a W3/CDG combo that required a good bit of milling. I dont want to modify another backbone as I feel it hurts the resale value. If you know of any other actions that are 100% "drop in" without the need for milling or modifying in any way, feel free to mention them as well.

I appreciate your help,
