I saw a Tai Ji 40 go today, looked very nice. Not a big fan of the small retracts on grass but once in the air it flew very well. On grass I'll stick with my Majestic (no tendancy to nose over with the stock gear/wheels) but the Tai Ji is certainly a good one. I've also flown an Aresti but the one I flew needed speed to do a good knife edge. Saito 72 gave it plenty of power.
