all of those are good boats... What I would do is demo as many as possible and take it from there.. That is such a long list that I would try to cut it down a little
If it were me
JK Hero
Pyranha Ammo
Fluid spice
B-S Scud
Here are my thoughts
JK hero and ammo are similar boats... Creeking boats with playoat hulls (awesome idea for a do anything boat)... Jackson has some comfy, comfy outfitting

and the new model hero's are sooooo nice, shortly after that the ammo for similar hull design and allround boating fun
The fluid spice and B-S scud are more river runners with different designs and would be more fiver running/vs the other 2 I mentioned (rr/play/creeker)... Now the nice thing with these boats is they will also go anywhere and do anything within reason. The spice is a little more playful than the scud though
Contact your local dealer and see what brands they carry, Bliss Stick doesnt have US shops as you buy through a local "agent"
Hope I helped
