do you leave pencil sized fruiting wood?

yes, of course.

frankly, some years I have seen poor fruit set due to too much rain and no bees at
flowering. it may not have to do with the pruning.

yes to that, too. This year I have a bumper crop, what with the mild
winter and mild, rainy spring.
Probably the reason I did not notice any effect from pruning in the
fall is that Concord grapes lose nothing to winterkill around here (I
have six plants). My guess is that if you are well into the growing
range, before or after winter is the same.
