What about it do you like so much?
In comparison to MX-S for example? To who would you recommend it?
I wrote a review but I would say that G1 is the best rubber of the ESN generation that includes Baracuda, Hexer, Genius, Xplode, Vega Pro etc.
It is for people who want durable spinny rubbers and aren't necessarily looking for the fastest stuff. It has Tenergy like throw angles but with less speed and better blocking characteristics as it is less spin sensitive from the sponge catapult. But the price for value is where it really shines as you can get 4 sheets for roughly $120, making it a bargain in this era of overpriced rubbers which may suit pros but does nothing for amateurs.
I think it can suit a wide variety of players - it definitely isn't as much work as MX-S to use. I know a guy who couldn't use anything but Tenergy until he used G1. It feels hard when it starts but it gets softer and the topsheet is very very grippy. It takes much less effort to get heavy spin.
