That's exactly how I am working with these forked terminals and I still managed to break one of the three fingers on one terminal (the only one so far - knocking wood). Only, I'm using desoldering braid; it takes longer but removes more solder. Plus, my old desoldering bulb is worn out and not as efficient as it was a few decades ago. I keep forgetting to find and buy another. Maybe I'll see if Mouser has any, since I now need some large resistors and terminal strips to replace the Candohms in this radio.
Speaking of J-hooks, I discovered something when replacing a resistor and capacitor at the 2nd IF transformer. Do you know the technique used by RCA to attach wires and components to the heavy wires coming out of the IF transformer itself? J-hooks! Yes, every IF transformer lead terminates in a J-hook. Imagine, the great RCA doing something like that.
If I don't forget, I'll take a close-up photo showing that later.

My T7-5 is American and uses those terminals on the tube sockets. Maybe RCA got away from those by the time the 110K2 was made.
