Growing black and gold raspberries together

I've read some conflicting info on whether this is recommended. Some say the blackcaps are too susceptible to fungal diseases from other raspberries and should be kept many meters apart. Others say that's a myth.

Has anyone got firsthand accounts of them being grown successfully together?

I've got blackcaps and fall gold raspberries I want to put in at opposite ends of a newly constructed raspberry trellis and they'd eventually grow toward each other. I'm a little concerned that being here in the rainy PNW (Vancouver) I might be more likely to run into problems, but I'm also of the mind that I don't baby my plants too much, I pop things in and let the strongest survive. I'd love to give the blackcaps their own spot but I'm literally on 1/12th of an acre so that's not happening. I could give them away if the general advice is that it's pretty likely to fail, otherwise I'd like to give them a shot here if the chances are good.

Thanks for any input.

I have several varieties that came with my property. I assume they are wild or rather maybe left overs from the old farm 40+ years ago.  Either way, I will find at least 3 different types close together, even mixed in with each other. I haven't ran into any kind of fungal issues or disease.  However, clearly if they can live together for 40+ years they must be decent varieties that very well may be resistant to things that might bother a new variety introduced into the area.

Thanks! Do you have blackcaps in that mix?

We accidentally planted Killarney Raspberries in with Black Cap Raspberries (about 1' apart).  What happened was year 1, the Killarney stayed super small and the Black Cap grew big.  Year 2 Black Cap dominated everywhere, so many!  Killarney was still alive, just crouching behind.  Year 3 (now), both seem to be harmoniously growing together, the colour of the stem is the only way we can tell who is who when there aren't berries present.  We've had no fungal issues from this, just very few Killarney (although perhaps this year will be different) and many many Black Caps.
