Graham Phantom DV XV-1s setup question

I took the plunge and moved from a DV XX2 MkII to the DV XV-1s :-) My TT is the TW Raven One. I have been playing around with the setup and currently have the loading at 100ohms, VTF 1.87gram, no anti-skate and no damping fluid.

After doing some searches read about the 2.5 tracking force option. I tried it at 2.20 grams for a couple of days and briefly at 2.50grams and it seemed to kill the dynamics. What I am experiencing now is slight thin/bright sound on some recordings, not what most people report as the character of this cartridge. Moving the VTF seems to kill the dynamics.

I've only had it now for 3 weeks, 20-30 hours. Is this the breakin character of the cartridge? is anyone using the damping fluid with this cartridge? how much if you are? Ideas? my phono stage can do 30,100,500,1000,47K.

Thanks!
