The Nike SQ Dymo2 fairway woods are a big change from the Sasquatch II woods and the biggest difference is the quad sole.
This sole is cambered from the centre of the club towards the heel and tow and then from towards the rear of the club from the centre of the sole.
This significantly reduces the drag from the sole of the club at impact, particularly if you are prone to the heel or toe digging into the ground.
Off lush lies this we find this a great advance as the cambered sole gives you lots of forgiveness, but off tight lies it probably does not help a great deal, and if anything makes the club feel a little unbalance.
Visually the Nike SQ Dymo2 fairway woods look pretty good and the square head does give a little move forgiveness than the standard shaped head.
