I am a big fan of the CD Solstice GTS, and I used that boat as the comparison to the Oracle, which is very similar in design. I loved this boat. I found it to be beautifully made and finished, comfortable for my 53 y.o. 5'9"/188 lbs, and as stable as the Solstice GTS. The Oracle is light & easy to handle off the water and very sweet in the water.
This boat is one for anyone who wants the Solstice GTS but is on a budget. Being 7" shorter, the Oracle is easier to turn than the Solstice GTS, but this is a boat for those who want tracking. It tracked great in very light wind. It edges as well as the Solstice GTS. There was no tendency to weathercock or leecock in these mild conditions.
I did not try the SmartTrack rudder as I was having too much fun going fast and straight without it. If my paddling was more of the expedition variety rather than day gunkholing, this boat would be my first choice if I could not afford a Solstice GTS. I don't know about the material so my rating is for the performance and fun.
