Narrative:

I was wbound on V44 crossing over top of stl TCA at 8500 ft MSL. I contacted stl approach outside of 30 mi veil for advisories. I was told there would be numerous aircraft opposite direction at 9000 ft. There were clouds ahead that I would not be 1000 ft above, although I could stay on top at 8500 ft. I asked permission to climb to 10500 so as to have VFR cloud clearance. The controller said no to my request. I was able to stay on top at 8750 ft. About 10 mi east of ftz I took evasive action (left turn) to avoid a widebody transport at my 12 O'clock and 3 mi. I now realize that I was flying against traffic on a STAR. I should have climbed to 10500 prior to overflying the TCA. I don't know why the controller didn't vector me south of the STAR a few mi. The top of the TCA is 8000 ft, which I thought meant that the arriving aircraft would be at 8000 ft or less when they reached the outer limits of the TCA. I didn't expect arriving aircraft to enter the TCA from above (where I was). I used poor judgement by using an airway that is part of a STAR, however, I would expect that the controller should be more concerned about the hazard I created.

Title: CLOSE PROX GA-SMA ACR-WDB OVER STL TCA.

Narrative: I WAS WBOUND ON V44 XING OVER TOP OF STL TCA AT 8500 FT MSL. I CONTACTED STL APCH OUTSIDE OF 30 MI VEIL FOR ADVISORIES. I WAS TOLD THERE WOULD BE NUMEROUS ACFT OPPOSITE DIRECTION AT 9000 FT. THERE WERE CLOUDS AHEAD THAT I WOULD NOT BE 1000 FT ABOVE, ALTHOUGH I COULD STAY ON TOP AT 8500 FT. I ASKED PERMISSION TO CLB TO 10500 SO AS TO HAVE VFR CLOUD CLRNC. THE CTLR SAID NO TO MY REQUEST. I WAS ABLE TO STAY ON TOP AT 8750 FT. ABOUT 10 MI E OF FTZ I TOOK EVASIVE ACTION (L TURN) TO AVOID A WDB AT MY 12 O'CLOCK AND 3 MI. I NOW REALIZE THAT I WAS FLYING AGAINST TFC ON A STAR. I SHOULD HAVE CLBED TO 10500 PRIOR TO OVERFLYING THE TCA. I DON'T KNOW WHY THE CTLR DIDN'T VECTOR ME S OF THE STAR A FEW MI. THE TOP OF THE TCA IS 8000 FT, WHICH I THOUGHT MEANT THAT THE ARRIVING ACFT WOULD BE AT 8000 FT OR LESS WHEN THEY REACHED THE OUTER LIMITS OF THE TCA. I DIDN'T EXPECT ARRIVING ACFT TO ENTER THE TCA FROM ABOVE (WHERE I WAS). I USED POOR JUDGEMENT BY USING AN AIRWAY THAT IS PART OF A STAR, HOWEVER, I WOULD EXPECT THAT THE CTLR SHOULD BE MORE CONCERNED ABOUT THE HAZARD I CREATED.
