The back of the neck isn't particularly figured (for PF):

There is some thought that tonally PF is quite a bit brighter than rosewood - closer to maple, but it's hard to really tell anything given the number of factors involved. I don't worry too much about those things as I sort of aim broadly for what I want to achieve and then believe in letting the result be what it wants to be. I always think that if someone wants a wood that "sounds like maple" then they should just use maple.
