True. If that's a Flite, I like the tips of those about 3 cm behind BB centerline personally. Tip of that saddle looks way back. Some folks like saddles way back though.

53 would probably work, depends a lot on tastes tho. I'm having troubles dealing with them modern brake lever hoods. Damn things are so long I have to subtract a cm or two from stem length to get the same fit feel as same bike with '80s SLR levers.
