I think they will all fruit for you Jeff at your location. The real question is how the quality going to hold up? Growing mangoes in Florida limestone soil and Florida climate is not the same as growing in Hawaii volcanic soil and Hawaii climate. I just posted same remark in thread about Rapoza inf Florida. Many people think that it's going to taste and perform the same in Florida as it does in Hawaii, and that's probably not true. And that's probably why many are dissatisfied with Rapoza mangoes in Florida.
BTW, you won't have results in 4-5 years. What you might have is a few tree starting to fruit. Results take at least 10 years, and sometimes more.
BTW, same applies to durians. Just because Musang King and Black Thorn are top notch in SE Asia does not necessarily mean they will be top notch or even fruit well in Hawaii.
