Everyone is different. Test it for a while and take stock on what you are hitting and how often you use it. I used to carry the blades up to the two iron in high school and it was an ego thing not wanting to ditch, that, let alone the 3 and 4 irons. Long winded, anecdotal way of saying try stuff and find what works best for you, but if the 3h flys like the 5i, definitly a good oportunity to get some other clubs in your bag that can help the cause.
