Well, if Ford league, i just had a similar situation. I had 5 type A's and 1 type B. They were all signed. I managed to snag the 20th, 24th, 41st, 44th, 45th, 46th, 47th, 59th, 89th and several other around the 120 range.
I stocked up my minor league positional players and grabbed a future star closer/RP.
I'd say it's worth it if A) You're trying to compete for a WS the year before (which i was...and lost in the WS. B) if you've floated out some of those type A/B's and didn't get much of a response and C) if you think you have a competitive team the next year (the year that the FA's are on the market).
