My 52" Stalker is about 52# at my draw and likes Axis 500 shafts 30" with a 170 grain head best.  I use a 200 grain head for high foc.  Again, I'd say this is less spine than a guy would typically figure for such a bow but this is what it seems to like.

I have both a recurve takedown and a takedown xcelerator.  Both great bows, can shoot a wide spine range. Every so often I try another bowyer but keep coming back to the Fedoras, esp if I want to shoot more accurately.
