First of all...apologies for having used DN instead of DG in the subject
..realise this is misleading for those trying to understand the subject! Yesterday I tried the DG on my Tachi for a short time but the result was not encouraging
...basically, when I was chop-blocking with the same wrist movement I use with the dtecs, most of the balls were ending long out of the table as if the combination Tachi-DG could not take the pace off the strong topspins I was receiving
Looking at the videos from Variatio I realise that his wrist movement with DG is quite peculiar...and I think I should try to do the same one although not so easy after playing for about 2 years with dtecs
Overall, DG seemed to me definitely faster than dtecs on the tachi (!) but maybe this is related to the fact that DG is brand new and my dtecs quite old...would be curious to try it on the Hydra once I've learnt the "new"wrist movement...
