In reply to Billg:
If the new infinity is anything like the old one (9.4) then I would get another one. It's going well after 7 years of hard use (chopped down at each end) and pretty much refuses to die. I tend to go for the dry treated for durability and handling so this may be worth exploring but it will cost extra. Can't comment on the Tendon, but I prefer skinnier ropes so would probably rule it out on that basis.
