I read that you are having a pull to the canopy issue on down lines. While changing thrust line will definitely address this issue, doing so will also effect every other trim aspect of the aircraft (up lines, level, inverted, etc.). So, you will have to go through another trim cycle if you want everything to fly right. However, have you thought about mixing throttle to elevator - if you have a computer radio that is? If you have the ability to apply a mix - try about a 1% down elevator at throttle idle. No need for a curve here - just down ele at idle. As the down line is established and at idle the down elevator is effective regardless of speed change. It is this increase in vertical velocity that is causing the wing to generate more lift and pull to canopy. That very small amount of down is also impacted by increased velocity and keeps things tracking straight. It has the added advantage of conditioning throttle management - something a number of sport flyer's overlook when they scream down from on high or toward the bottom of full throttle loops and rip the wings off.
