Pointing issues are related to leech control [on both jib and main]
By raising the jib, the sheet is pulling down the leech, giving it more tension, squeezing the slot, making you point higher.
this quite often leads to chocking of the slot which has a negative effect on speed. Methinks that the front monkey was not sheeting jib hard enough before or your jib leech is shagged![Maybe more than a couple of seasons old?]
