I can't yet comment on PW as I have just bought my first set for my trusty Columbus, but my 20year old Strat Plus Deluxe has locking Sperzels and they are superb! Never had any issues with them whatsoever and I often change strings on the day of a gig safe in the knowledge that my tuning will be sound. I would recommend them to anyone.possum1284 said:they are both terrible go with schaller or grover.
