Default Furuno 1870F and 1670F

I have a new 1870F which I have not used yet, but see that a 1670F can be had for $360 this month.

How much fish finder control would I give up, if I added a 1670F as a dedicated FF, compared to adding a 627 for FF duty, alongside my 1870F?

I realize I would have 480p vertical resolution instead of 640 (1670 vs 627), but we're typically fishing salmon in <300' of water.

I'm thinking this might be pretty good, for a minimal added redundancy?
