When using kitting, you can enter the weight of each product.
When a customer is looking at the kit and they select different options the price updates.
Is there a code to display the weight of the current selection?

Re: Display kit weight
Perhaps you need to create a control quite similar to ConLib/Utility/ProductPrice.ascx for weight that can calculate and show the updated weight and then use it in a very similar way as well.
