"I dont want to act impulsive and trade myself into a hole, but at the same time i need to have an unbias mindset and trade the rules that I have developed. Should I still take the trade if I have a strong opinion aginst it?"
"have others had this problem?,what do you do in this situation?"
The better not to have opinion of trades at all, usually the most difficult trades are most profitable. I made some research last spring by comparing the outcome of trades I took to outcome of trades I did not take. Actually, I missed the very best trades by making these "clever" quessings. After this I have tried to take all trades since only this will ensure profits.
