Hi, some input for you,
I am 195, 92 kg, so with gear that will be just below 100 kg.
So weight was not the biggest problem, only long legs and feet. Always an issue to get them stuffed in the boat.
I did my time in a Burn M, which will not fit you, I expect. It cracked twice in 2 years without a very obvious reason so I got fed up with Pyranha plastic. So decided to take something cheaper, an Eskimo Salto. In between I got new Five Ten creeker shoes (pretty big stuff) but still it fit the Salto but no room left. So that's also not an option for you.
With the Salto I also managed to get a hole in the bow so really got fed up with that plastic too

and decided to get a new creeker.
German Kanu magazine published their creekertest beginning 2011 and I selected 2 to test:
Prijon pure XL and Zet Raptor.
The Zet raptor was too small for my legs and feet so that left the prijon pure XL. At Bloem als checked the Jackson super Hero, but also, too tight.
First paddle strokes on flat water showed no flaws, the boat was spacious, tons of room for myself, my feet and all kind of luggage. On top of that, the prijon is known for its very solid plastic, so hopefully no cracks in the hull anymore.
But after 4 days of steep Creeking on Sesia tributaries and 3 additional winterdays of paddling in the German Eifel I found out that the boat is too big for me. With < 100 kg the boat is not deep enough in the water to benefit properly from its hull shape.
Last weekend, during the last winter trip in the Eifel, I switched for some hours with a Burn L owner and the good feeling was back.
So decision is made, boat is for sale and I expect to but back an Burn M or L, not sure which but I will have to accept the weaker plastic.
Summary for you: I expect the kanu creeker testers did their job properly and the prijon pure XL is a good creeker for the large to very large paddler. I just happen to be too light

You could give it a try, the boat is in Lent, near Nijmegen. Look at kanoforum.nl for the for-sale-offer.
Other alternative: Burn L, only weaker plastic, Burn Shiva, no personal experience but good reviews.
