Yup 5kgs is good. There's this one guy I've seen a vid of, he gives advise with bass fishing, he's caught over I think it was 800 10lb bass, now he's 1 lucky guy!!! I'll share the link for that vid in a few mins.
It tells you his name & how many bass over 10lb he's caught in the 1st 10seconds & then there's also some advise on night fishing after that. Seach ' the bass professor ' on youtube for other video's. That link is to download the vid.
