For a GlasStone progression I would start with the 1k 4k 8k 16k you can always go back and add the others if you catch HAD....
The other way to look at the progression is get a low grit cutter like the Norton 220/1k or the DMT 600???? then get the Shapton 2k 4k 8k 16k
Either way will work just fine....
Personally I use the second progression only because I grew very, very, comfortable using the Norton 220/1k for damaged razors....
If I were comfortable using DMT's I would have gone that way because they can be used as lapping stones too....

SOOOOooooo many choices
