I like Gewo and I cannot lie.
Then again, I like the Xiom rubbers mentioned too. The safety offered by the Neoflexx series is exactly their strength.
The Nanoflex series, at least the FT48, is still there and hoo boy. Lord of the Dance, a (relatively) unsung gem.
There are steps above, just like Vega has its Omega. A mere mortal will be tempted, but needs to reality-check every now and then and keep the merits of being able to keep the ball in the table in mind as well as the thrill of speed and spin.
