I have settled on the slotted SA saddles, now have 4 and have some converts with family and friends. Only problem I find with them is not keeping the minimum slot gap adjusted to the recommended 6mm. How can you go wrong when they will take it back and refund you money within 30 days which I did with their rubber version I tried. On ebay they can be a bargain if you find one where the slot is clearly too narrow and the adjuster bolt has not be extended which can lead to discomfort.
