Gary,
Lyre would be probably the best as chambourcin has an upright growing
pattern. If you use the GDC just make sure you have adequate space
between rows. There is a grower on this board who has chambourcin on
the GDC and uses catch wires to comb them down which is a good idea.
Just wait till after bloom to do that.Most vines canes' are tender
BEFORE bloom so as far as training the canes , be gentle before bloom.
Also, since chambourcin alwats has at least 2 clusters per cane and
the clusters are LARGE you could use the fruit to slow down the growth
and cut some off after veraison.
