I had the AK Rocket Swallowtail, mine was one of the last last made and had a wood-core. I also have a Volant Spatula, Fischer Watea 101, and Praxis Protest.
The AK Rocket Swallowtail is a great ski that rewarded a tail-gunner skiing technique in powder. The ski could turn very well in powder by sitting back and bringing the tips across the fall line. The skier could get back over the middle of the ski and accelerate once the turn was completed. The slot in the tail allowed the tails to sink and the tips to come up. The length of the ski provided great stability at higher speeds. The ski provided both quickness and stability on deep snow. On firm snow, the ski carved well and had a stable GS feel to it.
My problem is that turning the ski was like performing sit-ups. I didn't like falling back to create a turn and then pulling myself over the ski to maintain my balance. It allows fast turns, but it requires too much physical work. If I only had the legs of a 25 year-old.
Generally, I find that a rockered or reverse-reverse ski is more dependable with less effort in powder. The tips always stay up, no tail-gunning required. Turns are quick & easy, the ski produces a turn radius that mimics the reverse camber shape of the ski.
However, the rockered or reverse-reverse ski is never as stable at higher speeds or as ski-able on firm snow as a convention sidecut ski with a swallowtail. I wonder if the swallow tail was never fully developed. If the convention sidecut ski with a swallowtail could improve stability and firm snow performance without the huge effort penalty in powder you might have the ultimate soft snow resort ski.
How about a conventional sidecut swallowtail combined with a slightly rockered tip?
