Yes the Athena is a sweet shooting pistol, especially with all the factory ammo I tested with it. If you developed a super gamer load it would be even better!
I have shot RMR fmj, PD jhp, Everglades fmj and MG jhp.
MG jhp are my favorite and they are very consistent. So in my experience they are the most accurate for me. Never had any feeding issues with the jhp
+1 for atlas. All you have to do is call them and they will answer any questions you have.
JJ borrowed a nemesis from his student in 2018 and won lim nats with it.
Pretty cool stuff
The everglades holster works great and locks up solid. I feel confident when locked up I could run a marathon without it falling out. I also have a kydex hooded holster I use when I shoot 3 gun
I like the 155 but do not think they are essential to your kit if you already own 140s and 170s. 155 are nice to start with when you know you have to reload and want extra rounds over a 140 plus the extra weight helps a bit when it comes time to reload imo
