I think Keg, Lodown and Arm have the good oil here, Squall.
There are a couple of schools of thought on markers along your track. Some say 10 miles, others 6 minutes. Both work fine, but my preference is 10 miles. Use what suits you best. 10 miles are a constant, but 6 mins depends on your groundspeed and may vary from nav to nav or even leg to leg. Use what you're comfortable with. When I was taught, we only used 1/2 way markers, which made it much easier to miss the key feature/s associated with that point. Far less accurate than the abovementioned.
Read map to ground (unless uncertain of your position), using the markers described above. Try to have a key feature picked out for each marker.
As for features, work from large to small. The larger features are gonna be easier to pick out when it all turns pear-shaped.
Remember, big to small.
And have fun!
