Some Guidance needed - From Donic Barracuda to Yasaka Rakza 7

[J-fed]

In fact it seems like Baracuda is actually the spinnier of the two if you don't use the sponge as much.

That being said OP has been playing for a while, so it's probably okay to change it up and maybe find some blindspots in his game or technique. If he can make Rakza 7 work for him, he will probably learn something from it.

Absolutely what I'm saying to myself ATM.
I reckon we can adjust and get used to new equipment if we avoid getting frustrated and believe in the adjustments the we discover to be necessary.
In the process we understand more about the technical game I think.

Slow spinny loops can happen, you just have to adjust your stroke so that the blade angle is closer and you contact the ball very thinly and increase the speed of your swing to compensate for the loss of forward momentum. You could also try using some Chinese tacky style rubbers like the popular Hurricane 3. If you can't get slow spinny loops with a clean sheet of H3 neo 40 or 39 degrees hardness, you are doing something wrong.

Also keep hand loose on the slow heavy, it means everything. Get tip down, use fingers too.
