What is the use you have in mind?
I bought my first trigger back when the HiSpeed was all that was made. It's a DMR set. IT is the beesknees. It's in a 20" GI profile A4 rifle. I have total confidence taking it onto a target range, or social event.
Then l bought an SSA right after they came out. It's in my 6.8 recce. Nice but definitely not in the same league as the High Speed trigger. It also has my complete confidence.
I now have 3? SSA-E triggers. Nicer than the SSA but again not in the same league as the High Speed. If l have 3 you could say l have confidence in them too.
I've never tried the new fangled triggers introduced after the SSA-E. Never saw the need, for my uses, as I'm sold on the DMR High Speed and the SSA-E trigger lines.
After saying all that, the SSA-E would be agreat starting point.
