Candle lovers, help!?

i love candles. but every time i pick a candle (smelling every candle in the store i pick only one i like the best) as soon as i light it i understand that the smell is not really what i wanted and sometimes when its burning i can smell the smoke. i like wery light, not sweet smell. some candles give me a headache cause it's too sweet or... i don't know...just tell me what do u like! what do u think about new Glade candles. r they really good? thank u, everybody!
