Tom - The v3's (which I have) have more mechanical adjustability than the CSL elites. You can also get the optional brake performance kit which has different hardness durometers which replace the standard insert and can be used to fine tune pedal feel. I have it but have never used it as after adjusting the stock pedals I was perfectly happy with them, I run a fairly soft brake.
Other pedals to consider in this price range would be the Proto SimTech PT2 which have garnered good reviews from iracing members:
