Speed Trigger on Fly?

[endocrash]

I am getting an angel in a few weeks, but I am not sure which one to get. I have the money for the fly, but don't care about the LCD screen that much. I hear the trigger on the Speed is better than on the fly. Yes I already know about the mag job that can be done on the fly but then I would loose the vernier wheels, and is it really that much better? Does anyone know if it is possible to put a speed trigger on a fly?

Thanks.
