Hey guys I'm about to buy a new 14" or 16" NF round but I don't know what one would be more versatile in the golden triangle? I already have the little 12" round and I love it, its so stable. Recently I have just purchased a 5000 and I want to add to my arsenal of coils specifically greater depth for the Victorian areas. But I'm not sure whether to get the 14 or 16? Your thoughts on versatility along side the NF 12" would be greatly appreciated
