I was on the same boat recently so there is my fresh experience. For 2-3kg feeder, the best is still Sorento+Spark. Its truly amazing starting setup. Non-repairable but cheap to replace. Put on 4-4.5kg line. It will carry you to higher tier gear, fishing on Mosquito as there are the best cafeteria orders. Use the best available quality (stars) hooks up to S8 maximum to be safe. It's the quantity which make your silver and skill experience, not the big fish. You need silver to skill up bait and ground bait making. Do not waste money on mediocre gear you don't need. Instead of Lacerti 4000 (5.5kg drag) I would recommend saving a bit more for Adriatica 5000 (7.5kg drag) and the better low tier rods up to 16,5kg (Palmar, Fantazia FD or Persey). With that and 150-300m line you can fish the Grass and Black Carps on Old Burg with a bit of walking but it will not damage your gear that much and it's mostly friction brake damage. In my experience, Persey + Adriatica was more than enough for 15kg Grass Carp on 11.5kg line with 9.7kg FC leader. Yes, the reel is overloaded but you'll need to learn how to properly work with the reel brake and this is a good opportunity.
I don't do spinning but you generally want the best quality available to your level (still considering the weight relations between rod, reel an line) because the predators give your tackle a beating. And again, it's the quantity of "trash mobs" what gives you the skill XP and allows you to use the more profitable fishing methods.
