Narrative:

I had landed at kalamazoo and asked tower for a taxi-back and to pick up my IFR clearance to grr (grand rapids). Tower gave me a taxi route to depart on runway 9. I concurred and the tower gave me my clearance. While taxiing, the tower asked if I would be ready at the end. I replied yes. When I reached the end 30 seconds later, tower cleared me for immediate takeoff. So I began adding power while taking the immediate takeoff from runway 5. Runways 9 and 5 have the same overrun on displaced threshold pad. When in a hurry to depart, I took runway 5 which is a little further of a left turn off the hold short line than is runway 9. I had cleared the area for traffic and runway 5 was clear and the takeoff was uneventful. The tower made no comment after departure. I think the contributing problems are poor signage, my unfamiliarity with the flown aircraft as my job is flying a turbo-propeller with 2 crew membrs. When the time came to take an immediate, the magnetic runway heading was not crosschecked with the directional gyroscope, which was not set prior to takeoff.

Title: TKOF WRONG RWY.

Narrative: I HAD LANDED AT KALAMAZOO AND ASKED TWR FOR A TAXI-BACK AND TO PICK UP MY IFR CLRNC TO GRR (GRAND RAPIDS). TWR GAVE ME A TAXI RTE TO DEPART ON RWY 9. I CONCURRED AND THE TWR GAVE ME MY CLRNC. WHILE TAXIING, THE TWR ASKED IF I WOULD BE READY AT THE END. I REPLIED YES. WHEN I REACHED THE END 30 SECONDS LATER, TWR CLRED ME FOR IMMEDIATE TKOF. SO I BEGAN ADDING PWR WHILE TAKING THE IMMEDIATE TKOF FROM RWY 5. RWYS 9 AND 5 HAVE THE SAME OVERRUN ON DISPLACED THRESHOLD PAD. WHEN IN A HURRY TO DEPART, I TOOK RWY 5 WHICH IS A LITTLE FURTHER OF A L TURN OFF THE HOLD SHORT LINE THAN IS RWY 9. I HAD CLRED THE AREA FOR TFC AND RWY 5 WAS CLR AND THE TKOF WAS UNEVENTFUL. THE TWR MADE NO COMMENT AFTER DEP. I THINK THE CONTRIBUTING PROBS ARE POOR SIGNAGE, MY UNFAMILIARITY WITH THE FLOWN ACFT AS MY JOB IS FLYING A TURBO-PROP WITH 2 CREW MEMBRS. WHEN THE TIME CAME TO TAKE AN IMMEDIATE, THE MAGNETIC RWY HDG WAS NOT XCHKED WITH THE DIRECTIONAL GYROSCOPE, WHICH WAS NOT SET PRIOR TO TKOF.
