Never grown the pure sweet tooth. I have a hybrid of it going now. your local strain "CrossWalker" sounds awesome !!!! Never had the pleasure of growing that one as my circle is somewhat limited and I'm a good 2 day drive from Colorado.
"Heaviest yielding quality strain"
Subjective depending on ALL elements have to be in sync. You can have a heavy yielder and screw up on over fertilizing, overwatering, pH not being correct (in balance), weak light, air circulation, pests.
Concentrate on quality, for now, not quantity. That comes with experience.
