I'd go with ESTP or ISTP.. (as prev mentioned).
As far as NF's all being fuzzy bunnys, thats BS. If given the choice, I'd rather cross an NT than an NF anyday. While a healthy NF might be all sunshine and lollipops, the unhealthy NF is absolutely terrifying. These buggers can quickly see right into the very weakest and darkest recesses of your being, rip it out, waive it around like a flag, all the while dancing and humming "Kumbaya". Dark enough emotions know no bounds. Thankfully, most NF's prefer to stick to sunshine and lollipops
