No picking on the BP55K that I am aware of, however the previous version was picked by a chap called Beirhaus (not sure of spelling) and the lock was re-designed to block his method of attack.
MF has the info on the picking, but not the exact process.
Yes, it is a great lock, I have one and have owned a number. The older ones do have a better finish though. Shame they were discountinued, just too expensive to produce at around 600 euros, plus not conforming to magic module installation specs.
