If you don't try it to see for yourself, will wondering about what might be eat at you?
Since they have both been out of your system for some time
you may also find that the entire system will sound different
than you remember. IMO, you will need to give everything a
good several weeks to get yourself re-acquainted. Then make
cable changes once your ears have adjusted to the new set-up.
Either cable is likely to sound better in one position vs
another, only you can decide which sounds best to you!
All that I can say is that the further you go up the HFC lines, the longer it takes for everything to settle down after any motion in the cables. The HFC Ultimate References are a nightmare for reviewers, usually an A/B comparison has to be long term, namely over night. Mind you I love the cables, but my life is greatly complicated by this cost of using them.
