Need advise on predator calls

Lease is in Kiamichi Mountains of Oklahoma, lots of predators around.
Option A Foxpro Wildfire with Foxjack
Option B More expensive Foxpro
Option C buying a speaker and amp and connecting to Iphone and playing downloaded calls. the only negative on this one that I can see is no remote

I have a fx5. I don't think you can go wrong with a FoxPro

I have a Fox Pro Krakatoa. It's a really nice call, it's expensive but definitely worth the price. Pm me if your interested I have one for sale.
