After many years away from the big whites I have just ordered a 500 f/4 IS and now need to buy a suitable Gitzo tripod for it, I have ordered the Wimberley MkII $1000 AUD here and have to decide between two available tripods
The GT3541LS or its big brother the GT5541LS

Advice from those that regularly use this lens please, should I go for the heavier duty or is that overkill.
Thank you.
