Cool. I actually bought one of these
http://www.fishingtackle24.de/product_info.php?cPath=0_24_29&products_id=10445&language=en last year for similar type of stuff but only ever used it for punching lures in super rough conditions. It's a really nice rod to use actually, only the 3.6m version though so more a light, telescopic rod than actual bolo, and I imagine (knowing proper bolo rods) you're thinking much longer. These are designed for saltwater rock fishing though! The casting weights are deceiving as they're only high mostly because of the length. The tip is very soft and the power is lower down. I'd go one step lower (TE5) for saltwater float fishing though.
I think that strung-out shotting patterns could have a lot of use, even without floats where any OTD fishing is involved. A lot of people will have to learn to thread their casts, but should be ok.
With a float and strung out shot, obviously bites will show straight away. Nice. Everybody loves float fishing too ;-)
It'll basically be coarse fishing all over won't it. Suitable float shapes etc (i.e. long and slim), cane of carbon stems. I reckon that wacky hooked Senko's could be a good bet so they're more balanced and sink more slowly. Floating, mono lines etc etc. Size of float will obviously be dictated by depth. Helluva lot of variables. And that's just when using smaller soft baits. Moving vib baits etc is obviousuly a different story, as is trotting baits down in current. All totally different techniques, as you know.
