Pruning blackberry canes

A quick question: is this an OK time of year to prune blackberry canes?

I spent the weekend clearing a massive blackberry bramble and constructing a 2-wire fence to tie the living primocanes to (pics coming soon). Some of them, however, are 10-15 feet long.

From what I've read, you want to prune (or "top") them to the height of your fence. But the readings disagree on when you should do that (I've read late fall, winter, early spring and late spring).
