HDV to Broadcast BetacamSP

We are producing an press kit of footage for a client that was shot in HDV 1080i60. Unfortunately, we have to ingest it via firewire and go from there. The final medium for delivery to TV stations will be analog BetacamSp tape. So what's the best workflow to get from HDV which is UPPER FIELDS to Analog NTSC which is LOWER FIELDS without having field issues?
We realize we have to have a 4x3 centercut version. The issue remains what codec to edit in and output to miniDV or HDV tape, or a DVCPro deck.
We have a local dub house that can make dubs from HDV tape, but will that transfer introduce artifacts?

We have an Avid Adrenaline HD, and handle HDcam and HDV 1080i60 footage quite often.
We capture everything either HD SDI or HDV (via firewire), to Avid Media Composer and edit keeping a center cut safe. The Adrenaline has HD downconversion options, so we select center cut and do a digital cut of the HD timeline to Beta SP.
Another option is to get a hold of a Sony HVR-1500 HDV deck. It has internal downconversion options and SD SDI output.

So here's a question you'd think I would know the answer to. I assume you keep the edit timeline in UPPER fields. Do you have any interlacing artifacts or issues when you downconvert to BetacamSP?

Not that I've ever noticed on the beta's we've made and sent out. The adrenaline seems to be doing a pretty good job of the downconversion.
Other times that we've downconverted out of the deck and captured via SD SDI, I haven't noticed any problems either, it seems to be getting the field order correct.
Other times, we've exported a QT in Avid's DNxHD 145 format (upper field first) and converted using Canopus Procoder, to a SD centercut format using lower fields, Procoder does a pretty good job changing the field order around.
