oly vs nik

hi all

i've just set up a photographic printing buisness but i'd like your "personal" opinions on dslr kit for my personal kit:

my curent personal kit is e3, 12-60swd, 50-200swd, 50 macro

which would you spend the money on

1) 7-14, 14-35, 35-100, 90-250, 150, 300, tc1.4, tc2.0 all SHG glass

or

2) 14-24 f2.8, 24-70 f2.8, 70-200 f2.8, 300 f2.8, tc1.4, tc2.0, d300s, d3s, d3x

both work out to about the same price in the uk £18,000
needs to withstand harsh weather conditions.
i shoot 40% nature, 10% portrait, 20% landscape, 10% sports 10% other

i have a pretty good idea of which system i'll get but i'd like to hear your views.
