I've heard Superlight is way too light. The Lightweight is 75W80 (which is already lighter than the 75W90 specified by the factory). Superlight is 70W75, and doesn't have the friction modifiers for the synchros that the Lightweight has. So, likely it will shift poorly and be too light to protect the bearings.
I'd just deal with the Lightweight's thickness in the cold. It's not terrible if you're just patient when shifting into 1st and reverse in the cold. In fact, for the protection afforded, all the shockproof oils are generally better in the cold than the equivalent SAE oil. Remember that Lightweight shockproof's film acts like a 75W140 weight oil.
