As long as they punch equally hard you will do well against the intended targets of this model, when you start trying to make the hunter hit more often but not as hard etc or do other crazy things with him it detracts from the effectiveness of the model as a whole.
I totally agree, that seems like the best way to go!
On another thread, Wifstrand and Morkash came up with a build that illustrates this perfectly :
"Giantbreaker big name, Gold sigil sword, Enchanted Shield and Ironcurse Icon."
Giantbreaker makes the hunter a harder hitter, Gold Sigil Sword makes sure he hits first in most cases, which complements nicely the impact hits of the Stonehorn, Enchanted shield makes him a little more solid and the icon, even though it's only 6+, can help save both Hunter and mount from a nasty cannonball... Charmed Shield could work as well, but I prefer enchanted just because the idea of a Hunter with a 3+ armor save makes me smile.
I haven't tried it yet, but I'm currently modelling my Hunter on Stonehorn to carry exactly those...

Oh, by the way, was wondering, if the Hunter has Giantbreaker, does the +1 S affect his spear? or would we use his basic strenght?
