What level? With this many limpers I would guess 22 or 33.

Unless I had a good read on all the callers I would have just completed. You have three people (plus the BB) who might call you and would certainly be ahead. Even if it is only 15% per caller plus 5% for the BB that is still being called and most likely losing 50% of the time. Now if you complete and BB checks you are in family pot with a pretty good family pot preflop hand.
