I agree with most comments here about heather, its basically veryb hard to control. At Glasgow Gailes for example its like a carpet on both sides and its no way even a given that you will find your ball. More often than not a side ways hack back onto the fairway is the only play. The lack of recovery options gets old very quickly.
In contrast other courses, like Silloth, the strength and reach of the heather is more variable. This brings chance more into play, and why not if you've hit it off the fairway, but also allows aggressive recovery shots on a lot of occasion. I may also add that the patchiness of the heather is more attractive to the eye as well.
