I am going to reserve a few more from the MWRB file. I have identified 15 more numbers which are weight > 400 and SNFS-219 to SNFS-250. This still leaves lesser SNFS jobs for others, though moderately difficult, should they choose to tackle them.

That's what I've been doing. So far as I am aware only RichD and I are factoring these anyway.
