I got some brake levers and found out that 2 finger could actually mean 3 finger, so I wasn't happy about that. Then it turns out that the index finger trigger of the shifters I got are roughly 28 miles long. I pushed the brake and shifter as far inboard as possible and I still barely have enough room to get my index finger on the grip. Nowhere have I read that this is a factor, but apparently it is.
The reason I got these Acera shifters is cause the indicator window is on top which I thought was neat. Is this something I should have known about? Maybe it doesn't help that the grips I got have a little "horn" on the outside. That takes up maybe 1/2".
