I am not usually a big fan of the 7 to 8 inch blade size
I think the only knife I own in that size is my tt regulator.
I live in a temperate rain forest and about 80% to 90% of the time I spend in the outdoors is in temperate or alpine forest with the rest being semi-arid
For my own uses I find the combo of a 4 to 5 inch blade size and an axe/hatchet works best.
The only chopper I own (not including machetes and billhooks) is kershaw outcast that I have used for years (1311 is on order).
Other than the cool factor I just don't know how practical a solo blade set-up of 7 to 8 inches really is.
Of course different climate zones, have different types of vegetation so the ideal blade set-ups would be different
