on the Korean Spring Scale, 52g springs are VERY light -- lighter than Reds (Reds and Browns are equivalent to ~60g korean springs) because Korean springs are based on the weight at which they bottom out, as opposed to actuation weight which is what Cherry measures. People who are really weak are perfect for 52g springs (I personally have never heard of 52g springs. I've heard of 62, 65, 55, and 45g Korean springs.
