I don't think you can go wrong with 4k/8k and bbw/coti combo/ lapping with dmtc i find is exallant tryed the norton one and not as nice. At least yo have manmade and naturals to play with then you could get some ch.5 oxide. bevel setter i'd prefer the nanwa 1k to norton 1k because the norton 1k is very porous. If you would prefer same brand then get full set of naniwas they are very easy to use and learn on the choice realy is yours i have them all except shaptons which i like the looks of and it is a nice system but a little more money if i brought shaptons i would want the pond gdlp and holder thats why i talked my self out of it.
