Cardiff Blues coach Danny Wilson was happy with his squad despite their pre-season friendly defeat by Newport Gwent Dragons.
Wilson made 13 changes at half-time in a match that provided eight tries for a summer crowd.
"We used our squad in this game and I needed to see players perform," he told the Cardiff Blues website.
"Dragons are in a different place to us because they know their squad while I am still learning about ours."
Dragons scrum-half Sarel Pretorius scored two first-half tries, with Adam Warren and Charlie Davies crossing after the break.
Rhys Patchell scored the pick of the Blues' tries with an outstanding solo effort, with Josh Navidi, Macauley Cook and Rhys Williams completing the try scoring.
