I was never really into D05, I found it a bit too slow (high arc) and spin sensitive for my tastes. Vs D80, Zyre is a bit of a different animal, the contact time is short, but the spin is higher than D80 with the right contact and the speed is about the same or higher as well. The thing with Zyre is that there is that shot where you go hell yeah and then there are some shots where you go WTF... I think in the end, the quick ball release discourages lazy play and it is worth getting used to the contact point adjustments if you put in the time. But if you want a quick fix and you are used to the slow ball release of Dignics, the solution is not going to be fast or easy for you. But I think liking D80 made it slightly easier for sure. The flat play of Z03 is better for me as I like hard sponge, it takes a higher level of spin for you to be bothered, you feel like you are playing with short pips sometimes when the opponent isn't putting heaving spin on the ball for you to respect.
