Franziska ZLC is, depending on the weight and playerstrenght, slower for most players. The ZLC fiber offers more speed but you really have to hit deep into the racket to achieve the speed. Also many say it has good touch in short game similar to a wood blade and has a "second gear" if hit hard. It offers decent dwell.
ALC due to its outer composition needs better touch and can be faster in some instances. Mostly short game.
Feedback would be less and proper skill is needed. It does play a little more linearly compared to PF ZLC.
(Please feel free to correct me if I'm wrong)
In my opinion the FZD ALC is better price to performance.
Franziska ZLC and Dignics 05 should be a very good combination. Spinny, powerfull and high dwelltime should result in a "easy" to use but deadly setup. Also one that costs a fortune.
It might be helpfull if you could somehow tell us your skill and playstyle. Maybe what you have been playing before and what you would like to change. A budget would be nice aswell.
So we can further finetune the recommendations.
