On whey isolates.
For someone on an ultra-high protein I don't think an isolate vs. a regular whey protein "mix" will make much difference except maybe post workout. I would point out that (despite what the below article states) it is not correct to say that an isolate digests "better" or "easier". It could be absorbed faster, that's all. Except for pre or post workout, where it may be an advantage, in the end it comes down to a higher protein percentage. However, as I have been saying, in many cases there is a big downside to this because of the way these types of processing alter the whey. With isolates one could easily be replacing a high quality protein with something that a bodybuilder normally would be calling a low quality protein if they knew the facts -- and paying more for it!
Here is a little something more on this, which I think SHOULD be considered if you are going to spent extra money on an isolate.

Whey isolate proteins have seemingly overtaken every supplement store shelf in what seems to be an overnight success.
If you solely rely on a mere whey isolate proteins for your protein supplemental needs you may not be achieving your optimal requirements & results from your hard training.
Whey isolate protein by itself & in it self DOES NOT contain enough nor all of the necessary amino acid pool in order to achieve optimal results or to supply your body with all it needs to repair & mend itself.
Also, make sure you are using a whey isolate version that yields the highest amount of undenatured protein available. Many if the isolating processes, destroy much of the sub-fractions & do not yield as complete & high of an amino acid profile. So check on the process of which you chose to derive you isolates from. The above is why some people still claim that whey protein concentrate is still the best overall protein source. But WPC, does not yield nearly as high protein percentage per gram as does WPC, also WPC is higher in fat, carbs & lactose than a properly selected whey isolate. I can not go into detail here as to which isolate process is the best, as certain processes are licensed to particular manufacturers.
A properly selected whey isolate alone contains high amounts of ßeta-lactoglobulin, alpha-lactalbumin, Glycomacropeptides, Immunoglobulins, Bovine Serum Albumin, Lactoferrin, Lactoperoxidase, Lysozyme and & a high amino acid profile All of which are very important in heavy training athletes, as these compounds can aid in reducing running the risk of over training & aid in the digestion process. Whey isolate also gives a “quick” boost in aminos as it is digested very easily & rapidly, so it is good to use post training when your body needs that quick boost of aminos to replenish itself. But that does not mean that whey itself covers all the basis & aminos needed to optimally repair broken down muscle tissue.
