Since bolt handles seem to be involved and I am not familiar with some of the actions in question I went and looked up ones mentioned in this discussion Who ever designed the Nucleus and/or the Atlas gets a Blue Ribbon for the word ugly. Beyond me to pick between those two. However, I have 3 Pandas and must say the attention and customer service I have received at Kelblys is the finest. I could live with the ugly bolt knob (I think) to get the customer service.
Kelbly Atlas Tactical, Bighorn/Zermatt Origin, ARC Nucleus and Defiance Tenacity are all worth looking at.
As far as the TT triggers - keep an eye on it. Lately they've been having an issue with hangfires and misfires. So much so that they've had to create an "enhanced warranty program" - https://enhancedwarrranty.triggertech.com/.
