Hey Mickeeand,
Just putting the finishing touches on a 4*60 (biy kit), hard call here. The venture is a bit classier looking, and the quality of the materials is VERY high, but the kit is pricey, and you need to buy the optional kit for 2 wing servos, as the kit is designed for a single servo. The 4*60 is kitted strictly as a dual servo setup. Personally I avoid a single aileron servo setup like the plauge, but that's just me. I can say the 4*60 wing is a strong design, and both are a "turbulator spar" design that improves low speed performance, though some guys go to the trouble of sheeting from the LE, back to the main spar "****ettaboudit" bottom line you can't lose with either kit.
Good luck[8D]
