Raspberry cane advice

I'm highjacking Broadway's thread a bit so forgive me.

I have two fruit cages each with two rows of unknown unremarkable summer raspberries with the occasional autumn fruiting cane. None of which I paid for I'm considering digging up one row and buying some autumn fruiting canes to replace them. Contemplating actually spending some money is rather unsettling, so I was hoping for your recommendation for a sweet large fruited autumn raspberry not worried what colour. I see Veggie likes Joan J.

Grew Autumn Bliss first but, after being introduced to Joan J. there was no going back. She's bigger fruited.

Sounds like a contender. Thank you.

Joan J as well, nothing comes close in my opinion

I second that motion, it will be Joan j.

Say I ultimately want approx 10ft row,  how many bare rooted plants? Don't necessarily  need a 10 ft row immediately.

So if we say 20" apart for each plant in your row then a 10' row would need 7 plants? I think my maths is right there.

or may be 6 if you leave 10" each end for the end canes to expand into.

I have Joan J growing reasonably well and really like the taste. With a view to diversity has anyone got any experience of All Gold or any other yellow raspberry? Or in fact any other recommendation for a sweet raspberry. I will move some wayward Joan J to the new space when it's available but thought it might be good to have a second variety.

I grew yellow raspberries when I first planted this garden - still have them running wild. However, I don't like them. They taste of sweet water, there's no real taste to them. Also, the yellow drupes show all the black blemishes that would be lost on a red fruit. Don't let me dissuade you though.
