Marc, we did the same. It looks like you have the same spring bar as we have. Original we want to go for a tail dragger but we installed the springbar on the aft side of the fwd spar. We have defntly not an issue that the plan drops with 2 pob and no fuel on his tail. You can install the spring bar in two position. 1 if you lay it flat on the ground the middle is wider than the side where the gear is on. 2 if you lay it to the ground and it is not flat, now the wheels whill be further away from the nose gear.
Whe installed the gear like position 2. I think for my plane it is not that right because we have a bit mor weight on the nose gear. So check this! Good luck with your decicion.
