Nikon 600mm f4 help

[Walker Noe]

Hello all. I recently had the amazing opportunity to pick up a Nikon 600mm f4D AF-S I IF-ED for the delicious price of $2100, including a Jobu 2 Gimbal head. It weighs in at around 13 lbs, but I'm 20 and have no fears of handholding the beast for shorter periods. That being said, what are a nice pair of legs I should consider for my setup, especially since the lens has no VR? Right now I have a 300f4 and a carbon fiber set of legs, and I want to upgrade to something beefier. Would also love to hear others' thoughts on this lens, considering it's 20 years old. Ideally I would pick up one of the VR versions, but that simply isn't feasible on a college student income at this time.

Also, I'm 6'4" so that can become a factor in picking a suitable set of legs.

Thanks,

Walker
