Looking at the structure of Nevil's Haze and another haze I have that purportedly 'comes from Sam's garden' (and looks a lot like the ones that passed thru Nevil's hands), then compared to various Thais that are available, I agree with Sam that modern Haze doesn't appear to have a lot of Thai in it. Haze has an elegant xmas tree shape with great symmetry and the potential for colored colas. Different Thais have different structures, but I've yet to see the elegant xmas tree shape or the colored colas. Although I acknowledge the truth that some Thais and Colombians share more similarities than differences.
