Now Wales flanker Sowden-Taylor predicts they will seal a third Anglo-Welsh win by sinking Leicester Tigers in their EDF Energy Cup clash at the Arms Park.
Sowden Taylor, 26, said: "We have been building momentum and improving our performances. First it was Sale, then Gloucester and now we face one of the biggest challenges in Europe against Leicester.
"We've got two home games and we have to make home advantage count. Our ambition this year is to win a trophy."
Cardiff Blues coach Dai Young has given injury-plagued Sowden-Taylor the nod over veteran Martyn Williams in one of six changes.
Both were included in Wales' Autumn Test squad but Sowden-Taylor knows a big performance will attract national coach Warren Gatland's attention.
Sowden-Taylor, capped five times, added: "It's great to get a chance and I want to show Warren what I can do."
