I had just been asked "What's the best weight to get a good ROI"?
I replied...Let's start with what your market wants and work from there.
Easiest to give first what the immediate market wants and see how you can work around that. That way, the market is around you and no need to transport nor spend for information campaigns far and wide :)
As you are getting known, then educate them and introduce the weights you want. That way, you will give them options too.
