Salutations fellow Canonites!
I recently got my hands on a Canon EOS 1Ds which has it's shutter block replaced and serviced by Canon at quite an incredible price. However now I am at a stand-still as to what lenses I should mount on to it. Starting fresh in this day and age, I've used a plethora of Canon L primes (14mm 2.8L II, 24mm 1.4L, 35mm 1.4L, 85mm 1.2L II, and the 135mm 2L) and know these are all very capable lenses, but never used any of them over a FF sensor -- only a 1.3x crop (ref. 1D Mark III). Unfortunately, I no longer have the Canon gear I did a year ago so I am quite literally starting fresh in the dSLR market but my heart belongs to Canon so here I am. 
I shoot primarily on-location/studio portraiture and for fun, do some rural landscape work and fine art photography (as subjective as that may be). For my portraiture work, I do use off-camera lighting but I'm not sure if that is relevant to my inquiry or not; just trying to cover all bases here. Anyways, so here's the question...
What lens would you suggest to someone who has a 1D series body, true angle-of-view advantage of full-frame coupled w/100% VF coverage and shoots the subjects that I do?
I have a preference for primes, but it is not essential that the suggest be one.
Thank you to all who lend me their advice for near-future purchasing ventures!
