Ah, these pics of other balls made me want to find one I loved at high school but no joy so far on google.
It was a purple and black thing with the classic hexagon shapes only they were printed on and not actual stitched panels. They were a lot heavier than those flyaway ones, possibly even slightly heavier than a regular ball. They seemed to be highly pressurised too and they'd bounce higher than normal in the cages we were playing in.
The ball had a slightly rubberised texture too which I loved because they'd give good 'grip' to your feet when shooting. Can't really explain it too well, but if you wanted to do a curler or put some swerve on it I liked grippier balls in general rather than slippier ones as I felt you get better purchase on them rather than them sliding off your foot almost.
That's why I liked playing with slightly clapped out proper footballs more too, where the panels were beginning to get scuffed up. Not only would they grip your feet, but also the ground so you could put spin on a pass and have it bounce to the left or right slightly more like a spin bowler in cricket. With a brand new shiny thing that wouldn't happen and it would slip through off the surface more without changing direction as much. Got an Adidas Tango Scorpion when I was a kid and hated it for that reason at first on grass, when it began to get slightly worn it was brilliant.
