Finally tried out the 8.25 Crob this morning. To be honest, I barely skated the last few years, it was my only session in a while, and my long thin legs were incredibly lazy, so this is probably not the most reliable opinion.
On a side note, coming from the 7.5"/7.75" boards era, it's the first time I have an 8.25". I would say that the extra width is finally not too much for my 12/12.5 shoes and was quite enjoyable.
Anyway. About the twin shape, I never really had the feeling that I kicked a nose in normal stance. It's more like a long tail, maybe...it didn't feels strange at all, and I just had more room for my back foot positioning. In fact, I always felt my tails a bit too short with standard shaped boards, so I really appreciated it. Can't wait to try out some tailslides! As a front tip it just feels like a classic nose without any weirdness, nothing more, nothing less. Flip tricks and noseslides just felt good.
I thought the steepness was really on point, not too steep, not too flat, just the right amount to match a nose and a tail...
Honestly the weirdest thing about that board is that you don't have to bother the way you ride it.
At this point I can't say that I'll never go back to a standard nose/tail shape, but I have a really good overall impression so far.
EDIT : a (almost) new twin in the wild - AWS Frankie Spears, based on the original Owlien Twin it seems, 8.375" and 8.5".
