Narrative:

Widebody transport with flight plan only mcw JVL2 ord climb to FL410 turned to a 120 degree heading for ord spacing 40 mi southwest of mcw out of FL398. Small transport at FL390 10 mi west of FOD wbound. I realized widebody transport's climb rate had slowed. I turned widebody transport to a 020 degree heading for traffic. Widebody transport was out of FL400 climbing to FL410, I also turned small transport 50 degrees left for traffic. I took over the sector 3 mins before the event. Better awareness in a slow sector would have helped!

Narrative: WDB WITH FLT PLAN ONLY MCW JVL2 ORD CLB TO FL410 TURNED TO A 120 DEG HDG FOR ORD SPACING 40 MI SW OF MCW OUT OF FL398. SMT AT FL390 10 MI W OF FOD WBOUND. I REALIZED WDB'S CLB RATE HAD SLOWED. I TURNED WDB TO A 020 DEG HDG FOR TFC. WDB WAS OUT OF FL400 CLBING TO FL410, I ALSO TURNED SMT 50 DEGS L FOR TFC. I TOOK OVER THE SECTOR 3 MINS BEFORE THE EVENT. BETTER AWARENESS IN A SLOW SECTOR WOULD HAVE HELPED!
