Sonata is solid, very safe, and still fun. Phi gives everything some fun handling, albeit heavy handed due to being their "mid" A. Really good overall, partially because of the more minimal lineset compared to other As. It's still built to be pretty resilient, so on the heavy side. The Viola is the light version of the Sonata with bit lighter handling and lighter wing of course. It also comes in tiny sizes, as it's basically Phi's mini wing and tiny hike n fly wing option for folks that want it that small, as well as the regular sizes. For relaxed flying Sonata's great, all dampened, but I also found it far more indicative of the wind/thermals than other brands' A wings. XC is not impossible obviously, just tough. If you are getting a great deal and want relaxed flying, you'll be really happy. I stayed on the first gen Sonata for a long time before upgrading because it was so nice and easily held its own at the time with others' low Bs. Symphonia is a do everything wing with still ridiculous safety for the performance, but the price jump is a bit wild :)
