Def cue change over tip change imo. Different cues have a different feel to them. A different weight or balance plus kick point in a shaft (sorry the pool term escapes me rn but for golf shafts it is called kick point), will all affect the timing of your delivery. You can feel like you are doing the same thing but with a different tool in your hand, the effect isn't the same. Get used to the new cue and you will be drawing it just fine imo.
Have you tried them back to back confirming it isn't just something you are doing? Some cues 'fit' better than others. I mostly use 3 cues but only one feels like butter with my favorite technique to use and I seem to have best timing with it and consequently highest quality of spin. That said, I can rip the ball back with any cue, it's just the amount of spin at low speeds that varies between them for me and again, that is a timing thing for my stroke and how it fits my move rather than difference in the equipment performance imo. I could have gone full Earl and just blamed the cues in the past, but when my #1 baby was in for repairs for a while and I had to play another wand, I eventually figured out how to stroke it and get my regular results anyway.... different tips, different shaft diameter, different weight, different balance. They all work fine. You just have to get used to whatever you're using.
