As an aside, I also strung a frame with Head Sonic Pro 17 (happened to have a pack of it) at 35 and did not like it. It was definitely easy power, but I just didnt have a comfort level with knowing where the ball was going to go. And, the strings moved on the first point....I was constantly adjusting them. Many many balls went long. I switched to the previous frame mentioned above at 59 lb, and immediately was hitting much much better shots.
With some time at the low tension I would bet, like many others, Id get used to it and adjust accordingly, but think Ill stick with smack dab in the middle of the recommended range for this frame and just have fun.
