Yes – the 5000 is pretty much the same as the 1600 gritwise, I can’t say what difference (if any) the 5000 would give over the 1600 as I have not ever really looked, but the 10000 sure does. It would be good if Naniwa did an 8000 as it would give a good progression from the 1600 and then to the 10000.
I wonder if Clay would consider do a 10000 only Naniwa Chosera to cater for those with the 1200/1600 given that 1600 is pretty much 5000
