Blaze or Phantom?

I'm looking for a bit of advise from the floor here.

I'm hankering after a bit of spray this summer after a break of far too long. I didn't manage to get to the show at the weekend as my eldest decided she needed to move out of her flat at very short notice. I digress.

Anyway with no show input I can probably put new boat lust aside. I'd really like to get an RS100, but think I should test my sailing abilities before I spend that much :)

I sail on a river (or will be doing again) with it's usual attendant problems of moored boats, muddy shallows and fluky winds. I'm 6' 17stone of pure lard at the moment. Although I'll tart myself to anyone for a sail, i get annoyed with others when sailing, so single hander is a non-negotiable requirement.

I've always had a thing for ICs but I think I'm old and wise enough to realise that an IC with no experience on a crowded river is probably just asking for difficulties. I'd also need to be an awful lot fitter and nimble :)

Which brings me to my 'sensible' choices.
Blaze or Phantom. I've had wooden boats before, so I think I'll be sticking with plastic this time. but which one? Should I be considering other options (No I DON'T want a Solo, thank you very much).

Thanks in advance for you thoughts
