In the 2022 experiments, three distinct shatter heads were selected with focus on testing the effect of different fragment size \& velocity distributions on the disruptions. Overall we observe the highest assimilation of the pellet material and the highest radiated energy fractions for the $12.5^\circ$ head [1 - 3]. Hereby, the strongest impact of the shatter head geometry is visible in the low neon doping range ($< 1\%$) where a transition in disruption behavior is observed [3]. While the Toroidal Peaking Factor (TPF) is decreasing with increasing neon content in the pellet, we observed an increase in toroidal asymmetries among the more distant measurement locations - which is not well represented in the single TPF-value [3]. An essential part of the ASDEX Upgrade SPI project is the close coupling between experiments and modeling: DREAM [4], INDEX [5], and JOREK [6] simulations help interpreting the experiment and benefit from comparing results. For the 2025 experiments, two $12.5^\circ$ rectangular shatter heads were selected to investigate synchronized/staggered injections in more detail as well as an upwards pointing $25^\circ$ rectangular head. The $25^\circ$ head intentionally misses the $q = 2$ rational surfaces, key to understand the material assimilation/transport and necessary to further optimize the ITER DMS. [1] M.
