This information is based on a very limited sample of two Superposed Superlights, a 12 ga made in 1969 with an inertia trigger purchased used in 1978 and a 20 ga with a mechanical trigger purchased new in 1974.
Both triggers gave a signigicant amount of trouble, to me and to friends who shot them. They were both sent to Browning for repairs twice, returned after about a year each time and still gave problems. I no longer own them.
A 12 Lightning with an interia trigger purchased new in 1970 and shot much more extensively than the two Superlights on the other hand has never had a trigger problem.
The twenty gauge Superlight was too light for me to control well, probably due to my normally shooting much heavier guns. The stock had a drop at comb of around 1 3/8 inch and fit me well.
The 12 ga Superlight had much more drop than the 20, and more than the Lightning which has around 1 1/2 inch. I shot it with a Meadows Pad to raise the comb.
My experience may not be typical but here it is for what it's worth. I suggest that if at all possible you shoot a Superlight for fit before you buy one. You might also be cautious about Superlight triggers.
I personally recommend Lightnings rather than Superlights.
