As for your question about ladder bar adjustment, the lower the front of the bars are to the ground the less prone to wheelie, but the limit in fixed length only dictates so much return by lowering. You are trying to get as much below the neutral line as you can get possibly get your front mount.
4 link is the best for custom adjustment's in respect to tuning to a multitude to different power levels but your ladder bars may still be ok for you if you are able to lower your front bolt a few inches lower or the very lowest possible mount would be the starting point.
