Looking at these picks...both are tortex, both come in same gauges, both have the jazz III tip, both appear to be roughly the same size...the only difference I can even see is that the shoulders are shaped/placed a little differently.
Am I missing something here? I wouldn't think Dunlop would put to market such similar items but what do I know!
Just an update for those that were interested (read: no one )...I've assorted a huge amount of picks to experiment with. As it turns out the Jazz XL is actually slightly smaller than the TIII picks. Size wise the picks go from smallest to largest: normal jazz iii -> Petrucci Jazz III/Jazz III XL (the Petrucci is EVER so slightly smaller) -> Normal pick/TIII
