Guys..I have a question..I have US visa, but I have never been to US. If I do flagpole will that affect my future entry in to the US? Like as in previous entry denied or something like that.. Also is it better to land with or without car?
There is no any issue for your future entry to the US at all. Just use COPR and passport for flagpole, the officer will never ask you about US visa. Not too worries. ;D
If you choose to flagpole, you don't need a US visa at all. It might even be quicker than getting your passport stamped by the US, I waited 1.5 hours at the US side to get my stamp/I-94 card. Whereas the landing at the Canada side took 20 minutes.
