Thanks, king.
In my personal opinion - the Panthera / Dynamic block rifles are the absolute pinnacle of what today's airgun market has to offer. They are definitely the best platform for almost anything due to their power potential, versatility, and infinite configurability. You can have it be a .177 peashooter or a .357 deer dropper, and anything in between. I personally prefer the Panthera/Dynamic over the DRS (as of today, this could change!) for NRL22 due to the finger-adjustable and excellently designed precise hammer spring adjustment plus having more on-board air to chuck heavy slugs and not worry about efficiency much. I am just starting to dabble with the DRS and don't have very much time behind the rifle, for what it's worth. But my Pantheras have been 100% reliable and they don't just sit in their cases - I use the bejesus out of them and compete 2-3 times per month in addition to hunting (with my Hunter Compacts), etc etc etc...
POI shift isn't really something that should deter you from buying one. That will happen with any airgun, and most firearms even - especially if you absolutely SMASH it against something as hard as I did at nationals. It was the full weight of the 15lb+ gun plus me falling into it. Yea.... it was bad. Haha. Hopefully I never do that again, especially during a match. I have learned to be very careful and deliberate with my movement due to the PTSD of that incident!
