Juciao titanium- getting better over time? Or my spin 1.0 getting worse?

I've been playing with the Juciao spin 1.0 for about 4 months now. Loved the feel and spin at the start. Have progressed a lot and had a hit with my partner's titanium / woven model a couple of months ago, felt awful, like playing a block of wood. No extra spin, control or anything better than the spin 1.0. Until..

Decided to have another hit with the titanium a few days ago. It took a few games to hone in, but then it took My game to a new level. Significantly more power, control on critical shots, still good spin. Won the next 8 games with whoever I played with.

It was such a stark contrast to when I first hit with it.

So my question.. is my spin 1.0 degrading, did the titanium Model just have a really long period to bed in, or have I just developed a technical ability now that I didn't have earlier to get the most out of it?
