My bag does not have Pro in the name. I tried it again since posting about it and it is useable, just a bit snug. I also tried it with the hood on in shooting position and that also fitted so I would say go for it.

Pros: tall, very sturdy, built in tilt head and QR plate, extra little legs that store in the shaft that can make it self supporting if required.
Cons: heavy for a monopod, not as compact as say a Gitzo traveller, the little legs rattle in the shaft when stored so I wrapped a bit of tape around them to keep the noise down (or just don't carry them if you don't intend to use them, saves weight too).

Having recently purchased a Sigma 150-500 I have been playing around with it on an assortment of tripod heads to see how well they worked together. My experience of using long lenses is limited but I have accumulated a small assortment of tripods and heads (to take this photo my K5 was mounted on a 50 year old Gitzo tripod with a tiny Ising pan head that must be more than 60 years old).
Anyhoo...FWIW here are my initial impressions of using the various heads with the 150-500.
Front row left to right:
Gitzo 1780 centre ballhead
Obviously a bit smaller than ideal but actually coped quite well, useable when travelling light. Fiddly QR mechanism.
Manfrotto 468 hydrostatic head
Works as well as any centre ballhead can - smooth with fine control over friction. Only disadvantage with a long heavy lens is that it has free movement over 3 axis which requires extra care.
Gitzo 1276 off centre ballhead
Pretty useless for this weight of lens - movement is just too wild and hard to control - excellent for other applications but not for this.
Back row left to right:
Gitzo 1372 pan/tilt head
Very good indeed - the ability to isolate just the pan and tilt movements make for smooth precise control.
Manfrotto 322 pistol grip head
I have fitted this head with the adaptor that allows it to be used both vertically and horizontally. In horizontal mode the centre of gravity is lower but it feels very awkward. In verical mode it is great fun - just like a game consol joystick- but the centre of gravity is so high it feels like the whole setup could easily topple over. The other problem is that you can only move the camera by gripping the head, so I kept finding my shutter finger was not free when I wanted it. It could probably do with a shutter release on the head trigger.
Manfrotto 393 gimbal head
This is purpose designed for the job and does it well. It is big, heavy and ugly but allows for very smooth movement in 2 axis which is just what is required. The only issue I found is that because the Sigma changes length as it zooms you have to re-balance the gimbal for optimum operation every time you change focal length (or just make sure you don't let go of the camera). For some perverse reason Manfrotto advertise this as a monopod head when it works perfectly well on a tripod. In fact I found it quite tricky to set up on a monopod, although once set up it works fine.
Unfortunately I cannot comment on using a Wimberly head for the simple reason that I do not have one....it is hard to see that it would be that much different from the Manfrotto 393 though, except that it's not so big, heavy and ugly (and costs 4x the price).

and
DA* 300 f4. I don't use long lenses a lot but the stunning results I have seen on the forum from this lens make me long to own it. Perhaps one day...

Sigma 50-150 arrived this morning, well packed and in excellent condition. Thank you.
Pity Matt has to sell up because that was a really nice kit.

A modern version of the old classic A* manual lens. I can't think of anything else.
