As mDiyo said, FTB is not updating because of red power 2 and red power 2 won't update, or you are stuck at 1.4.7, and no I don't think there is version for 1.4.7 .
Have you looked a ftb recently there are packs for 1.5 .
You put leather and string with the bow into the tool forge and it gets the "quiver" modifier. Now you can put Arrows in and it fills up to a max of... maybe 4 stacks? If you shoot then it consumes these arrows. And maybe there is a chance of not consuming an arrow, like 5, 10 or 15%?
Hope you like my suggestion and you did some great stuff with TConstruct! Keep being awesome
Maybe the more luck you have it gets better like fortune 1 having 10%, fortune 2 having 15% and so on.
