I agree it will give you more choice and more tuning range in the overlap/mid area.
Exactly the same with sail quivers. I probably belong to that group that spread out their quiver quite a lot. Example: 4.2-5.0-6.0/slalom 7.3-9.0. Another example: Kombat86 + 75cm wide slalom. (and it works) But it was my choice to cover as much conditions as possible, rather than to concentrate on specific, most important area.
As you say, an individual thing (and a $$$ thing also).
Sorry it was maybe OT a bit.
