I also like your #4 Line up. The 24-104 is ideal for outdoor walkaround on a crop body--I have one and love it. The 135L provides that beautiful bokeh and outstanding IQ for those special and artistic moments and the 50 gives you the low-light ability when needed.----But.......It would be very hard for me to pass up the 70-200 II if I was in your position [:S].
Good luck,
