TigerS is a mid-firm, aggressive rubber with lightly tacky topsheet that keeps its tack well through extended use. Probably the best combination of spin and speed Air offers.

MambaS is the hitting rubber of the new Euro series. Perhaps similar to AssassinS in that it relies on mechanical grip, making hitting through spin easier. Whereas AssassinS has more of a matt Japanese finish, MambaS has a more glossy, euro finish.

KnightBee uses the thinnest topsheet of any of the air rubbers, making it the lightest Air rubber and easiest to produce topspin. Even though the sponge is 39deg, the thin top lets the ball sink easier. This is probably the Air rubber that plays the best right out of the package.

TigerS Unlimited is a more "Euro" version of TigerS, featuring a less tacky topsheet, compensated with a softer version of the Air Red sponge. Easier topspin than the regular version, but a little less spin on serves and pushes.
Now available in BLUE! (can only replace red; one side must be black)

This topsheet has a Euro feel with traditional Euro pips structure and very light tack. Good spin (even on serves and pushes) without being sticky at all. Available in two hardnesses of sponge. Alpha version is 41deg, Delta is 35. The true strength of Illumina rubber lies in its control while countering or blocking heavy topspin.

DefenderS is a spinny control rubber currently available in 1.5 as a defensive and 2.1 as a control looping rubber. My favorite of the bunch, personally. The topsheet isn't sticky at all after initial use but is grippy. It seems people who used Japanese rubbers prefer defender, and I've had comments that it plays best with the plastic balls. It isn't slow and really shouldn't be named Defender. I'm told the better translation was "guardian" or "shield". NOW IN 0.6 too!

The Assassin topsheet is similar to Illumina, but a little firmer so it's overall faster and slightly less spinny than Illumina.

We're returning Scirrocco to it's original vision of a semi-tacky, top quality rubber. The impeccably made topsheet pairs nicely with these harder 47deg sponges. This is a thicker topsheet on a harder sponge. Lots of power for those who swing big, but also heavy at around 72g so you probably don't want this on both sides.
OUT OF STOCK 2.1mm

This is the version of Illumina used for the Premade Busters. It uses a mid-soft cake sponge, 35deg. To bring it at this price, it is coming unpackaged.

The Arthur is Loki's top line of rubbers. The Asia version is the tackiest. It features a 41deg grey, porous sponge that is listed as a "carbon sponge". China version is slightly less tacky with a softer red sponge, and the Europe version is again less tacky and slightly softer, black sponge. All versions are listed as 2.1mm (max). I'm also going to throw RXTON5 PRO on here. It's only made in black. Very nice, not really tacky but very fine, grippy topsheet, blue sponge mid hardness.

Rxton 3 is a nicely made and packaged rubber at a discount price. The topsheet looks nice and is lightly tacky. The sponge is a medium orange full thickness.

These are genuine DHS rubbers, all in the NEO series:
H3 has a lightly to barely tacky top, not terribly thick or heavy, especially compared to their traditional counterparts.
H2 is a harder, tackier, more traditional Chinese rubber.
TG3 is a little less tacky, more often used for backhand.
OUT OF STOCK TG3 black

Well-reviewed as gambler's current best offering. The "T" version is lightly tacky and the "M" is mechanical grip. The T version also uses a different white sponge marked as "hard," but it doesn't seem any harder to me, or at least not that hard. I do prefer it to the normal orange "Oh Toro" sponge that is under the M version.
OUT OF STOCK VoltT 2.1 black

Japanese-style offering with the quality Oh-Toro sponge. Non tacky, but somewhwat grippy. The 9ut is a little tacky, pretty nice. Mechtek is available in 1.9, and NT in 1.7.

New version. Zero is light, totally non tacky and not real spinny but a little because the sponge is soft.
OUT OF STOCK 1.7

Gambler's newsest top-quality line is the "Gold" line. After trying a couple of variations, the forums seemed to pick Diamond as the best variation. Lightly tacky, with a very high quality sponge.

Traditionally a hard, sticky rubber, it would seem PF4 has been transformed into a rubber "made for the new ball." I guess that means not sticky and much softer. Now, to me, this rubber feels like a high quality beginner rubber, something like Flextra. Nicely made, though.
