one of them is the BRINKS 1 9/16 laminated, its actually harder than i thought it would be!
im finding it hard to find the right ammount of tension, if i turn it too much then the bottom pin gets stuck at the top, and if i turn it too little it doesnt bind at all! anyone else ever have a go at this one? note - still a beginner!!

the second one is an American Lock Company Series 5530, this ones giving me trouble too!
any tips from people who have beat these? i have opened the brinks by raking and single-pin picking, have yet to open it just by single-pin picking
