Glad I could help!! The trajectory issue I understand with drop but i will say the one handy dandy tool i ever purchased was the hamskea 3rd axis leveling device. It can be used to check all the axis’s on your bow and sight. When i shoot uphill or downhill i have always aimed dead on and have not hit high or low unless my form was off. Archery i have always seemed it to be like saddle hunting its very personalized, and can be modified as a user sees it. Im a tuning junkie when it comes to bows and have spent years upon years in the shop and helping people of all levels (i take pleasure in the success others achieve). What works for me may not work or fall in line with others but i just like to add my experience in hopes it will help someone else.
