18:1 is the standard/"original" ratio. (TM's and such)
~13:1 would be speed gears (use a high torque motor. no really, you read that right.)
32:1/72:1/100:200 etc would be torque gears (for pulling stupidly strong springs, wouldn't be legal anywhere in Canada)
then again, maybe I just read ASM too much and think 50+bps @400 fps is normal.
