Fallout – Does carry weight affect stealth

This seems to vary from item to item. From my testing so far, I've concluded the following:

• Arm piece will add +5
• Chest piece will add +10
• Leg piece will add +5

Your ability to sneak is directly effected by the weight of the armor you're wearing.

In most cases, it would be better to have lighter armor equipped.

If you have at least rank 4 in the Science! perk, you can modify your power armor chest with a stealth boy. This greatly increases the stealth capabilities, and would likely outweigh the stealth benefits of wearing lighter armor.
