I've been running HV-LiPo/LiHV in my touring car for about 6 months and haven't noticed any difference.
Yes, you aren't allowed to charge them above 4.2v per cell at any brca event and the capacity is based on being full charged to 4.35v per cell,
But they are lighter than standard LiPos and because you don't full charge them they are far less prone to swelling. Most swelling occurs when the battery is fully charged, this is why LiPos should be stored about 3.7v per cell (3.8v for LiHV)
One thing to remember is to change you low voltage cut out to 3.3v per cell or you can over discharge them!
