Ray: A lot depends on what you want to do with the scans. Print or post on the internet or make slide shows to let's say a UHDTV or HDTV? If printing, what size? How many pictures will you be shooting? what's your budget for developing and printing and scanning per year? Also, what kind of photography? Street, landscape, nature, travel? Do you plan on using a tripod?
With the inverted WLF with 120 format, I always use a tripod, even mostly with my 35mm gear. I do mainly cityscapes and landscapes with the occasional portrait. If I am printing I like to print at least an A3 or 16x12'ish. Usually go thru about 10 rolls a year, a roll a month'ish, I simply import the film from the USA b/c here is nearly 3x the cost, I then develop myself with a Paterson tank, cut and sleeve myself. I also shoot slides whereby I import the film again and shoot maybe 10x rolls maybe more with 120 format, let's see since there are less frames and I export to the USA for processing ie $10US per roll developed and $2.50-4.00US per roll delivered back dependent on how many rolls I ship. If I am going to outsource the scanning, I would only do a few scans per year. So the most are just scanned with the flatbed. I heard that Hasselblad scans cost around $15US per scan.
The Epson V700 doesn't impress me. I used to have a Coolscan 4000 before, before it broke. Bought it used off a pro. A night time cityscape shot. You look at the building logo names. The Epson was just not sharp. The Coolscan is so much sharper. If I sized them to 1024x768 I cannot tell them apart. If they are 1080 to match our TV or posted on Facebook at 1080 there are differences.

While you could get a certain size job with a flatbed. Is there just something lacking after going thru expense and effort of shooting film.
Edit - I recalled one time when I had the 4MP Nikon D2h and the D70 on a separate occasion (6MP) against some slide film, all on a tripod etc. Scanning the film with the Epson even the 4MP camera had more detail at a 1080 size. A modest blow up print does the job but if there are these the tradeoffs why bother with film photography if one is limited to a flatbed.
