If Liteplus is a brand of Litepro, those might be ok as you say, but my feet would slip off those pedals - I got rid of the original Dahon folding pedals, because my feet kept slipping off, and I didn't want 80's style toeclips, or to get specific shoe types in order to clip my feet to pedals. Limiting, especially in a collision. The treadplates of FD-7 pedals are grippy, even when my shoes or boots are heavily mudded from gardening. They're very sturdy pedals. Heavier? But very well made.
The other useful thing about folding pedals is, (when folded) they don't graze your leg as you pass by your bike, when it's leant against the wall in hallways, because you didn't want to fold it, though with the G-Line you could remove the removable pedal, turning the bike around if necessary. Or fold it. You won't accidentally lose a folding pedal, unless a perp takes a fancy to it.
Also, you can fold either pedal if walking the bike, saves having to carry around bandages, tetanus shots and a blood donor of the right type. Having transported around the wrong type would be disappointing, but deadly for haemophiliacs. Brompton really should have thought this through. Around one in 2,000 men, women and children in the UK have a diagnosed bleeding disorder. And diabetes is rife, they don't heal fast. Fat legs are everywhere.
Distance from pedal to crank arm is pretty small (sorry about the mud), doesn't significantly increase Q-factor.
They've released an ultra wide version, available to buy out there somewhere.
