I haven't tried the 8'6 -but I do own both an allwave and prowave in 8'10.(Both 2013)
They are both great boards but very different.I bought the allwave for my son to use,and for a more relaxing option when I feel like it.
The prowave is just brilliant and I would say that one of the things that has really surprised me about it is how well it goes in small waves.I am 70 kg ,so a little lighter than you but I would consider the prowave range even if your waves are a little fat as you say.I don't think it needs hollow waves to perform.
I think that it is at least as good to paddle if not better,and picks up waves very easily.
The allwave is also a great board but nowhere near as responsive under foot.The major difference is that the allwave is very stable due to it's width,but as a result it feels like a lot more board on a wave.
I think the 8'6 would change this a little but I would consider a prowave as well.
You might have guessed that I'm pretty stoked with mine...
