DayValley,
Here are some of my experiences. If you have a great flow, take honey. Unless of course, you wish to expand your hives by 3 or even 4 fold the next year. (Thats what I'm doing currently, I already made 1 split, making another split next weekend, and another split about 2-3 weeks after that if things go well) I left them the first year all of their honey, and they exploded their population. I didn't even feed them in the spring, and about 2 weeks into the flow already, they have a super full. Plus, I live in minnesota, so the winters are very harsh. Another thing you can do is take almost all of their honey, and feed them before winter, (after the flow). Make sure if you do that you also feed them sugar in spring. If you can figure out how much honey they need for the winter, and you are able to take a little, that is optimal unless you want to drastically increase your beeyard.
