I Think amber bud trichones 55-75% is the best tasting smoke and the best high.I agree with Alienwidow
Looks like some more to go yet.
You should know this:
Do not look to the sugar leaves for tric coloring. Look to the buds them selves.
Have the buds expanded from the bulking phase?
Are the calyx's swollen and the pistils withdrawn into them?
So you have sugar leaves with amber tric's - are the trics on the buds all gone white or opaque?
If the answers are yes = harvest.
If not = not yet but look at them daily..

OP
If its possible to leave a few buds after harvest, and take one with each change in trichone colour, then once dried and cured, you can sample the difference in taste and high of each change..there can be quite a significant difference.
