Try the new SV3 Square and start hitting dead straight drives now.
Major Advantages of square golf heads are Long and STRAIGHT. You will find the new square heads very hard not to hit straight. USGA has a new limit on MOI for this exact reason.(moment of inertia relates to stability on off-center-hits. A key to maximizing moment of inertia is to push weight as far away from the center of gravity as possible.)
