well this is an exciting twist on Tring, sadly the LIDAR is less than patchy in the area;
The Bulbourne doesn't seem much of an obstacle anywhere along it's length, and flowing along the direction of march it wouldn't have had as much impact as the cross field rivers we've discussed at Mancetter and Cunetio. It may even justify the left and right wing principal a bit. However if that is the case couldn't we move the field down the valley relatively easily? Berkhamstead looks good too. The only plain I am seeing is that to the north of the Cow Roast site, the approach from the south seems a very tight valley in terms of the contours but the street view images make the side slopes seem rather relaxed, not a plain but fightably flat.
And if you move your Roman line south to the helmet, there are a couple of "iffy" looking cuts in the chalk;
It's moved Tring up the ranking for me.... but still not above no. 3
