well, i do like the speed king's internal compression spring, other pedals the spring stretches out, and i like the direct drive, yes the clamp requires a shim most of the time and it can cave heads or scrape heads depending on your setup. my main pedal has been a dw turbo 5000 for the last 20+ years, the regular round sprocket aluminum hinge, double pedal with the three uprights and the bent left pedal shaft. i recently got a newer double with roughly the same setup. but I usually like to time travel when im playing a 60's-70's set, so i opt for the Speed king.
I had a Ghost but was'nt thrilled no power. and the clamp was even worse!!
slingerlands strap pedal from the 60's 70's wasnt much better.
the only off-set cam lever pedal I have ever liked was TAMA's Pro beat from the late 80's early 90's, tama's camco/extra light was good too, right before the iron cobra pedals came out.
so in respect to pedals i guess im a Camco guy...
