To be honest a DSLR isn't for you, these are semi-pro level cameras (Depending on how much you want to spend) I'd get a great Point and Shoot with a long optical zoom, turn it on, shoot away, super simple and great pics to boot.
Most guys I know us a cradle to control the fish in the water while they get rid of the hooks.. Once they've done that, it's either back in the drink or out for a quick pic then off she goes!
I wouldn't worry about braid cutting in on your guides, unless they are from the 80's or earlier... Casting won't do that, bringing the line in under pressure will (ie while you are landing a fish)
I still haven't found a line that casts better then 6lb Nanofil.
Shouldn't matter, as long as it's a model they carry. They should still warranty it for you, or at least send it in to St.Croix if they won't provide you a replacement.
