Vienesse biscuits are my favourite as well especially when dipped in lush chocolate.
Scales are definitely essential for baking. Often the recipes online are from USA and they use cups, which originally I thought was so weird. How big a cup? Turns out they have standard cups, but thats still not accurate depending on how much you pack in a cup. I read some Americans say the same and think using grams and scale is much better, but I think maybe cups is too deep in their baking culture
