Low gear set 904, pro’s and Con’s

You will have a bigger drop on the gear changes, if your converter is plenty loose its likely not a big deal, if it is borderline that might erase any gains. Do you think a looser converter would help more than the gearset? I have considered the lower gear because my car is out of gear up top but my 60ft is a best of 1.41 and I don't want to mess that up. So in my case I could put a taller rear gear in and get my SLR back with the trans gear set. My car is 3550lbs.
