They are different. Dingtian needs boosting, but it's very easy to boost. 2 layers of FTL on the sponge directly and you are set. From Dingtian you can choose hardness while with LAC you are in the mercy of the shop. Maybe one can send a message to them what you want but since the package has no hardness info on it they are probably clueless too unless the "bigger" box they are shipped in has some label.
Dingtian boosted is "crazy super fast". If you put that sucker on an outer carbon blade you will overshoot everything. It only works on DHS HL5 type blades I think. Durability is excellent for me, 3 or 4 times reboosted and no bubbles, the topsheet looks like new. It has blue sponge! I mean that must be at least 2-3 points advantage mentally.
LAC, no need to boost. Not as fast but more stable and controllable. I feel like it has more spin and arc by default. It really plays like D09c in my opinion, in many ways better than BTY's "best". On W968 it has a lot of arc and a lot of spin, and I like that a lot. I am saying that maybe I will switch it to a faster blade that is lighter but I am having so much doubts about that. It feels excellent on the W968 and I guess that is why
@Attitude likes it on the VSEA too. I might just change the G-1 to the G09c since G09c is about 4-5g lighter than G-1...
Speed varies honestly, I can hit very fast shots with it, sure not as fast as with a faster blade with a faster rubber, but placement! With LAC I have placement. I can hit from anywhere to everywhere. That is not speed, but if the opponent has no idea where it goes they are losing precious milliseconds just reacting and I feel that is a much bigger difference than the extra speed of a faster setup.
LAC is better for serving and receiving.
LAC is great on W968, I am very confronted now. I like it on that blade a lot, I think I will just put G09c instead of G-1. W968 is a weird blade, it is kinda slow sometimes but fast in other times.
