Just picked mine up from Maxis Pavillion this afternoon....lots of reading & playing to do, if I'm not gonna root the phone yet...
Uncle Benny, pls add me to list of users!

Oh my god... Maxis Paviilion got STOCK???????
So, quick reviews are in order.
S-Line Grey Translucent - Cheap. Fit is okay and cutouts are acceptable. Side patterns are a great plus, as they add oodles of grip. The semi matte back means that it's not really a fingerprint magnet, and there's just enough transparent bits to show off the back of your SGS2. Buttons are stiff and hard to press though. Material likely to yellow over time. USB port a bit cramped, did not fit my USB-OTG wire without some adjustments.
Epikcase Jet Black - Cheap and generally similar to the above, except that it's glossy black and attracts fingerprints like moths to an open flame. The plain black feels and looks a tad boring. Has the the cramped USB issue too.
SGP Ultra Capsule - Except for two glaring faults and the fact that it's a fingerprint magnet, this is a work of art. Cutouts are examplary and the glittery finish feels exclusive. Buttons are super easy to use too. The USB port cutout is roomy and can fit everything.
Now, for the bad part - the thing is loose. Not so loose that your SGS2 will fall off, but if you're a like me, the looseness can be felt clearly and it WILL drive you nuts. Secondly, the lanyard hole is tiny and a hassle to use (I had to mutilate mine). Also, the corner hole is a disaster waiting to happen.
BUT, keep in mind we ARE technically using cases for the wrong phone as far as SGP is concerned. I'll be eagerly waiting for the world spec SGS2 cases from SGP.
SGP Ultra Optics - This is a WONDERFUL SP. It's even better then my old PowerSupport Matte on my old i4. It's darned clear and you never really see fingerprints on your screen. It's also matte enough to not reflect your own face while you're typing.
BUT, keep in mind that if you're the type of person to type while looking REALLY close at your screen (or just the particular type), the ultra optics have a very, very fine grid pattern to it, which is probably the microlense array itself.
On our not so retina screens, it's not really THAT noticeable however.
Samsung Battery and Charger - Samsung original korean spec batteries, with near field communications written on the back - and no it doesn't magically enable NFC lol. The battery charger also doubles as a stand, nice. I got from exportprive.com.
Can you take a picture and show us how is it look like after you apply the Ultra Optics?
