Not so much brand loyal, but tend to stick with lines where I have had good experiences and know I will probably enjoy again. Anything DPG / My Father come to mind here. Crowned Heads and LFD fall into this category for me as well. Some brands I tend to pass over becauuse I may have had a few I didn't enjoy as much; Rocky Patel might fall into this category, even though I have had a few that were fine. Then there is just plain reputation, like Gurkha. I am sure there are some great cigars with this name; but too many to pan through that disappoint in order to find that fleck of gold.
