In terms of raw technical specifications, Viton is probably overkill.
HOWEVER, it is a joy to work with and provides very secure connections to the stock (unbarbed) pipes.
ZIP ties were popular about a decade ago on FDs but IMHO are useless. The car I bought had and entire set and they hoses slid off easily with them. Once the rubber hardens the ZIP ties are just extra clutter. ZIP ties or hose clamps would only really make sense if the stock pipes were barbed.
Yes, Viton is a litter harder to get on, but once it is on it is going nowhere.
