I received the two Supreme CF 17 x 5.5 props yesterday along with two 1755 MKII Carbon Fiber Propellers.
On a 4014 KV 330 T-Motor both of the 1755 MKII props had significant vibrations and at 100 watts the thrust was 930 grams. They had good static balance but the mounting area was too wide for the T-motor washer's flanges so I had to use the washer upside down. The two holes in these props were 4mm instead of 3mm like the bolts on T-Motors. The center holes were a little loose on the T-motors shaft.
Both sets of props weigh 34 grams.
The two Supreme CF 17 x 5.5 props had very little vibrations.
The CW prop had 1030 grams of thrust at 100watts and 1130grams at 111watts.
The CCW prop had 1020 grams of thrust at 100watts and 1090grams at 111watts.
The thrust of these props is very close to the values the T-Motors gives in this chart for 18.5 volt or 5s lipos.

The Supreme props are very quite but I found that they both whistled at some point. The CCW prop whistle was not too loud while at 560watts but the CW prop made a lot of noise whistling at 980watts. 980watts will be very close to my hover RPM and it could be quite irritating.
I need to buy some T-Motors props to have more info but the Supreme props are quite good.
