My summer canes are about 3 foot high at the moment, while my autumn ones are still tiny ( because I cut them back in the winter). But if the canes haven't been attended to, it's anybody's guess what type they are at this stage. If any of the canes look like old ones that fruited last year, cut them out now (this applies to both summer- and autumn-fruiting types).
But you'll probably just have to wait and see when/if they produce fruit, and then you'll know how to treat them from then on.
