I cannot comment on the Racing 4 or the Hunts specifically. I only post this because of two previous posts. I love my Fulcrum Racing 5 and my Zondas are outstanding. I was looking at the Fulcrum 4, but saw the 5's and liked the specs and the fact they were lower cost. The Zonda I purchased because I all the 5 star reviews, the specs and they were on sale from PBK, at that time less than $300 USD shipped. I got the Fulcrum 5 from PBK on sale also, just under $200 at that time. Prices have gone up a good bit since then.
