Uni-Din is interesting. But although I am not sure that it's worth the effort.
In most of the records crescendo occurs in the very end (at least in classical and jazz) so with cartridges like SPU which are not the best trackers I do feel more safe to have Stevenson as it less possible that it will damage inner grooves of record.
My proposal is if you do any changes by yourself buy test record and use tracking tests as after trying different alignments you have to be sure that you haven't made some hard errors then aligning cartridge.
