Buying a DMT lapper, please help

[khaos]

I am about to buy a DMT for lapping and heavy duty work. My main question is, should I get one with or without holes?

Also is the 10x4 worth it compared to the 8x2.75?

From reading I have gathered:
With holes- far less stiction and swarfs up less quickly, but has fewer diamonds/area
without holes- more stiction, swarfs quickly, but has more diamonds per area.

Any advice? Any thoughts on the blade catching on a hole? I will not need a low grit hone frequently, so if its just that I should be careful, that is okay by me. I just want to know if its a very likely danger.

Between the four options price is not really an issue (I know there are big price jumps but all are in my budget I would like the best of the 4)

Also for what its worth I'm leaning towards the big combo holey one. Seems like while it has less diamonds/area, the decreased stiction and less swarfing would make it a more efficient lapper.
