the original slimlines (v12's) always needed a laser "fix" to prevent them from burning out. the new v13's no longer need this "fix".
as for which ones work with the slims i know
crystal 1.1 lite works on v4-14's
dms 4 lite v4-14
matrix infinity v4-13
duo 2 se 4-11
pm'ing you info on a supplier/installer
