The previous owner of mine installed the CalMini lift kit but didn't like the ride so removed the components from the front (kept the rear) & did the TB crank. Just wanted to give you another data point for your decision. I'll second Jo's recommendation. Go with the OME springs & put the savings away for the diff drop.
The rear track bar extension linkage could be nice ... but only if the lift shifts your rear axle to the side (it has happened but not sure if the track bar was to blame).
