2-3 yards a slice???  That isn't even a cut.  ....I still call it a fade if it is only in the rough...  ...LOL.

I vote adrenalin on course and your arms just a fraction ahead of where you are on the range, assuming this isn't an uphill lie.

First of all, If you don't already...practice more than you play. And about the slice, you should make sure that your swing plane through the ball is in-to-out not-out-to-in. If it is already an in-to-out swing plane then you should set the surefit hosel setting to either A3, D3, A2, or D2 (assuming your right handed) for a more draw bias.

Hips first.

Agree with swing plane

A3,B3,C3,D3 are all draw bias because the clubface is closed.   A4,D4,B4,C4 are draw biased for someone with a flat swing.

A2,B2,C2 and D2 are fade bias for someone with an upright swing because the clubface is open.

What a lot don't really understand is how to set up the Surefit.  A1 is the default setting.  What you could do to set up the lie angle is put some masking tape on the sole and observe where the scuff marks fall on a lie board..  If toward the toe, change the setting to B2 or A2. If toward the heel, set it to B1.  THEN you can set up for fade or draw (D2, C2, D1 and C1 are 1.5* open; A2. B2. A1 and B1 are .5* open, D3,C3,D4 and C4 are .5* closed; A3, B3, A4 and B4 are 1.5* closed).  You can set the lie angle statically also with toe pointing slightly up; if you have to choke down for a proper stance, then the lie angle is too upright.  If your hand is off the edge of the grip it is too flat. 

I use the A2 setting and hit it dead straight.  I actually get a higher ball flight with A2 vs D3 or A3 because of the slightly open clubface.

Andrew, that's no slice.  Sounds more like a beautiful controlled fade.  If its consistent, I would recommend you play it rather than fighting it or trying to change it.  Many of the best players in the world play a fade as their stock shot.  The Golden Bear being the most notorious.
