As I've used this Andro set-up for just a month, these are initial thoughts.
Spin is great which is why I selected it.
Ok speed could be higher but it's ok for me.
Durability after a month seems ok, there aren't any wear marks.
Would be an interesting comparison against so called 'King of Spin', the Tenergy 05.
It is 30% cheaper than the Tenergy.
Im using it as 2.1mm on both sides. When the rubbers need replacing, I might try Tenergy 05 on the forehand
and keep the Rasant Grip on the backhand.
