you could chose a stem with small buds in but nip all the buds out or they wont grow roots. its worth a try. also keep looking at the base for any new shoots or up the stem for side shoots. they work just as well.
I've had sour grapes before, it is lovely but i lost mine when i moved house.

not from the stem with flowers. you can take them from non flowering stems now. do you know how? or would you like help?
