The Trek is the complement (slightly more understable) to the Ascent. It should go to field testing in late April.
The Ibex is our mid-range. It's not quite ready for prime time, but I am very excited about our first cut.
Additionally, the Cairn is a new putter and is based on tweaks that were requested by some of the players/advisers on our team. No time frame for field testing and/or release date yet.
