Just a quick query please.
After many years of wanting too, I finally received a lock picking kit last Saturday. I also ordered a couple of training padlocks which I can open pretty easily now.
Yesterday I went to my local hardware store and bought two Abus padlocks. One was a 64ti/30 and the other was a larger marine style Abus lock. As soon as I bought them I managed to rake and pick both of them fairly quickly and was surprised.
Last night I sat down and spent the night practising opening them. The large marine one I can rake open in a few seconds. However the smaller 64ti/30 one now takes a lot longer and at one point nearly took me 20 minutes to do it. This was frustrating after being able to do it so quickly earlier in the day. The security level on the larger marine lock is 7 and I think the one for the small lock is 5 but I can pick the larger lock in no time at all.
I don't think either of them have security pins in them as I can't find any mention of them in any ads online or on the packets.
Is it quite common for a smaller padlock to be a bit harder to pick?
There were times last night that it looked and felt as if all the pins were up and it still didn't turn?
Any help or suggestions would be gladly received

Thanks
