Spitfire Wheel - ideal for coated/painted concrete or wood surfaces

I skate for close to 30 years now, am almost 70 and jam skate as exercise twice a week for 2+ hours. I needed new skates and got a recommendation to try Konixx, checked out my options and picked Spitfires as I am skating almost always on painted concrete floors.
Well, they feel like skating through sand - slow is an understatement. I immediately suspected the bearings that came with the new skates, but switching wheels to older Rinkrat Identities took the sand away. Obviously I ordered the wrong wheels, but the Konixx advice on what to pick seems way off the mark. If you do not want to compromise on speed I recommend staying away from Spitfires no matter what surfaces you skate on. They are sticky and may be durable, but effortless speed is crucial for any agile skating maneuvers - jamming or hockey!
