Weight of Ski attachments? (MSFS)

[HighburyYVR]

Hello, it may seem an odd question but as the title says I would like to know the approximate weight of the ski attachments. The purpose is so that when I am doing multi-stage flights from the south to the north of British Columbia (where I usually fly) I can simulate the weight of them as cargo when they are not fitted.

Thanks!

I'll ask Jim he may have an idea.
