Kowa Super 66

[garpet]

I've shot a fair amount of 35mm and was looking to get into medium format. If I got a Hasselblad I would be at risk of hesitating before doing stupid things to get a good shot - which I cannot allow - so I got a Kowa super 66 instead. Anyone have experience with this? I got mixed reports on whether or not you can use straps not originally meant for it to hold it. The handle for it is kinda pricey but seems like a near necessity from what I've heard (especially if I have to wait for a strap with connectors specifically for the super 66 to show up), and whether things are compatible with it even if they're 'for' the six is unclear. Also, the one I got is coming with the E-type grid screen, but id really prefer a split or micro prism for making sure I get critical focus (as an aside, what's everyones preference for split vs micro prism for medium format? I use a split prism for my 35mm camera, but I'm interested to know if my preference is likely to change with medium format) anyone have any actual experience with the II vs the III series focusing screens? It seems like they're both compatible with the super 66.
