Flip - the PR3's had a real issue with front feel, all down to the "sipes". I had exactly the same opinion as you.
Not long after fitting PR3's front and back I had a slow puncture in the front, the new PR4 was available so I fitted that instead. Totally different tyre and much better front end feel.
Still got the PR3 on the rear, 8k and still going strong!
