I agree, these are the 3 and can make a case for any order depending on preference. Personally, I'm a big fan of highland pines but biased because it's a new track.
The condition that Cypresswood is in right now would push it to probably the fringe top 3. Their Cypress course (2nd best of the 2) has been in immaculate shape lately.
If you count A&M as North Houston (LOL), mine would be: 1) A&M's course in the front of the campus 2) Tour 18 near Humble-old but fun (kinda like a hot ****) 3) Any public course in the Woodlands
Played High Meadow last Sunday they recently punched the greens and its cart path only which is working to try and keep the grass together as much as you can in this heat.
