unfortunately not.. if your setup is 1.7kg there is going to be some form of vibrations etc.... the 2kg limit of tripod is the limit that doesnt break the pod or topple it/spoil it but functionally speaking.. you have try the pods to know the strength/weaknesses
If you're going Benro, take a look at the A169m8 or A269m8 then. I think the travel weight is still ok at ~1.5kg and ~1.8kg. Of cos the A069m8 is very light at about 1.2kg ?
As Snoweagle, proteon and giantcanopy said, got to factor in the head's weight, consider for vibrations and mitigate the risk of overweight failure..... one other thing to note is that when your setup goes beyond 2.5kg, you'd need to change to another tripod !
I use a 12kg max load (Head + tripod) but my camera + lens + flash doesn't go past 2.5kg as yet.......
I have the same setup weight as you. In the end got a tripod that can support up to 5kg. The max weight is really not that useful. I'm sure I can hang 6kg on my tripod and it will not break / bend. The main thing is the stability of the tripod, and you have to test it out.
Another thing to note is the weight of the head (as mentioned), as well as having to option to hang a counterweight for increased stability.
