The owner himself said publicly in an interview back in August 2016 that he wanted a coaster with inversions that "would be a combined metal and timber one so you get the best of both worlds".What proposed hybrid plans? Are they anywhere on the internet? Not doubting anyone, but I never heard any rumours of a hybrid.
I also did hear ages ago about the plans being discussed with a manufacturer for such a ride. It would have been great but obviously though these plans fell through in the end. Its a real shame but I still think the STC looks to be a fun family thrill ride and should be popular with the park's guests.
But who knows if these coasters are successful and visitor numbers continue to increase in the coming years maybe they'll return to the idea of a more aggressive thrill coaster (be it hybrid or steel) when they can better afford it (given the cost of the cancelled 2019 plans were said by Ray Coyle in a late 2016 interview to be €17mill while this 2021 investment is only 14mill + the planning permission document claims high maintenance costs made another wooden framed coaster undesirable; cost played a large role in the change of plans)
