does your work prohibit the use of a tripod? if not, just go for the 2.8. If you;re worried about IS, because of the IS MARK II out now, the used 2.8 IS MARK Is are selling lower and lower each day. they still provide a decent 3 stop IS which functions well in this tele.
If you do not require the 2.8 though, the truth is that the IQ for 2.8 stopped down to F4 is slightly (very little) not as good as f4 itself.
personally, the weight isnt a problem unless you shooting whole day w/o tripod. tripod = shooe weightless but lug around a bigger arsenal. rent and test urself will solve this problem no problem =D
