Speaking of the new Titan I heard one on a S Yorke TT (not mine). THere WAS a Helikon there too, but that was hooked onto an Amazon/Morch combo.
What I can therefore say, is that the S Yorke/Titan had much better resolution in the mid-range and more extension, esp in the bass, especially in complicated orchestral passages (Mahler 8, to be precise).
The speed/pitch (PRaT if you prefer) was exquisite on both set-ups.
Oh yes, this doesn't answer the original question. Famaraca: little to add to the advice above, sorry. Assuming you're sporting a SME 4/5 arm or equivalent, go for the SL. The Clavis, good as it may be, doesn't match up to the SL.
