Resurrecting an older thread for the 2nd time - but can you please add a link to the replacement arca adapter head you installed? There are a million of them on Amazon and I like the look and weight of yours if I can find the same one in Canada. Also can anyone tell me what size the Allen head...
Just looking for an update on how you like the 5900, I am having the same dilemma myself have been using my brothers 6900 for the past 2 weeks in training but would love to hear from someone on what they think of the layout of the 5900.
Cheers,
Brian
