Kinda-sorta. I like the hard mounted needles and the bowl lids for convenience, the HIF's not so much. The floats & needles/seats in the HIF's are more hassle to service. Needles in the HIF's are intermittantly rubbing the jet at changes in RPM. It takes a long time for that to be detrimental (hogs out the jet orifice to an oval) but it kinda seems 'funny' to me. It also makes an odd kind of liquid/vapour column appear at the inboard side of the needle, a laminar flow issue. Not quite as efficient as the older, hard centered piston/needle combo. The "package" of the HIF's is neater looking, the flow characteristics are nearly identical, so really it's down to what you want/like, yup. If it were a car for a track career it'd be the older ones, if a street machine, it would be less an issue.
