Trichocereus Cacti Cutting types and comparisons

Trichocerus come in lots of variations, and I am in no way an expert! But I do love collecting and growing them, and selling them too!

The first 2 images here show 4 different types of trichs.  If you check most cacti forums, there is a lot of discussion on names, incorrect names etc. and sometimes it gets pretty messy.  If you feel my naming is incorrect, my apologies, send me an email and share your knowledge, it's always appreciated. This being said, there is natural variation amongst types based on simple factors like elevation, temps, soil, surroundings, sun etc.
