I have the sports, no flashing lights or twirly bits but they do the job, I think 2x8Gb will last you a good few years, you will probably upgrade to faster RAM rather than more RAM before you go to 32Gb
This is off techradar about them,

Just like the Tactical LP modules these wee Sport VLP modules are fairly sprightly at their stock settings, but also remarkably compliant when it comes to overclocking. Keeping the default timings and voltage and just changing the speed in the motherboard BIOS options to 1,866MHz resulted in a non-booting board, but a slacking off of the latency settings to 11-11-11-28 1T (still at the stock 1.35v) got the memory running rock solid at 1,866MHz.
Keeping the same CAS11 settings but altering the speed to 2,133MHz caused the motherboard, again, not to boot, but increasing the voltage to 1.6V got us to a rock solid (even when being pushed hard in the benchmark tests) 2,133MHz.
No matter what we tried to get a bit more out of our review modules, 2,133MHz remained the fastest stable speed we could achieve, but as with all things memory related, you might get lucky and find modules that turn out to be a bit more obliging.

The fact these modules work so well with tiny heatsinks - even when being overclocked - confirms our general feelings that all those lower speed modules with their large flashy heatsinks, are more to do with catching the attention of your wallet rather than any real cooling function.
Still, the overclocking prowess of these sticks is not really the point. The low latency settings, decent performance and incredible size make this a rather desirable little set. Low-profile, low latency and low voltage - that's quite a combo, and the added versatility offered via the overclocking makes the Sport VLP a great prospect.
