So I played the 315 now for a few hours including one tournament match and here are my thoughts on it.
I received my racket with about 5grams of lead at 12 and strung with Alu Power Vibe at about 50 lbs
Will try a more stiff string soon, but this way it was super powerful and also had quite some plow.
It is an interesting mix really, because the thick and flexible frame wants to give spin and power - the rather tight string pattern control and then the Alu Power Vibe offers great feedback but also some extra power.
Overall I had good feel but heaps and heaps of power compared to my H22 or the frames I usually use. I cannot really see a tour level pro playing this and not overhitting, sometimes when defending the ball sailed on me like crazy. But when attacking it offers quite some nice extra pop and as long as you stay in front and hit the ball with authority it doesn't sail.
Groundstrokes are all super solid, also thanks to the lead I guess but you can hit balls on the way up and still push for pace, get some decent spin or flatten out.
It has a tendency to sail balls out or spray them left and right, but only if you tend to back off or just lift them back into play IMO.
Serve is where the racket really shines, the flat ones are incredible + you can generate nice spin on both kick & slice.
On touch shots and volleys it is super stable but sometimes the kind of bouncy stringbed tends to give too much here. E.g. you want to play a volley stop but it bounces from the lively strings and at least if you are used to traditional 18x20 patterns this may surprise you.
The number one benefit though - it is super super comfy on the arm, without giving too much control away compared to the Clash.
But still this is not a control oriented frame that I see for a lot of competitive players.
I would say a very comfortable Pure Drive
