Astrological orbs and the Mayan prophesies?

Hi everyone! Ok double question! I'm aware of the advised orb allowances, but how do we look at 6 and 7 degree aspects? How weak are they really? I've a venus and Pluto trine of about 7 degrees and I feel it all the time, it's strong. Venus was exalted and Pluto was at home so maybe that strengthens their aspects?! Also, especially for those of us with Aries planets, what happens when Ur transits around the Mayan prophesy date? Ur is leaving my natal venus now and continues transiting natals for about ten years...I'm concerned about his plans for Midheaven, sun, jupiter, north node and mercury...anyone else concerned?! Lol
