Im happy with my FJ's for far. I have the MVP60 Advanced Adult model. I have had them for well over a year now and I have not had any issues with them at all. I am no pro or anything but I do use them as much as I can. I'm really happy with the easy replaceable rubber feet as I have worn down my rubbers a few times already. This is why I am happy I bought Fly Jumpers and not Powerisers or any of the other branD. It is too expensive to replace rubber feet with the other brands. They all want you to buy the whole bottom assemblies with the metal on it and everything again. I can't afford that every time I wear down my feet. With FJ it is only $20 for a set of new rubbers which is very reasonable.

  I get to give you my sales pitch here 

But honestly, our bocks are really good quality for the price. There are some better quality bocks out there but they are all between $800-$1900 for a set, especially for delivery in Canada. Some are even more expensive than that. We sell the best quality bocks between the $350-$500 range, our bocks have stronger carbon fiber springs (opposed to just fiberglass) and our replaceable feet save you tons of cash over time. Not to mention the service we provide for Canadians. We honor our warranties and stand behind our bocks. So Fly Jumper all the way man 

The MVP are sweet man, you will love them. I have had mine for quite some time now and they are really comfortable on the knees. Just be sure to setup your calf cuffs properly as I had problems with this when I first got mine. Check out this post for for info on calf cuff setup: http://www.flyjumperforum.ca/stilt-problems-and-solutions/frames-feel-warped-when-i-run/

Apart from the cold temperature the winter time is really only dangerous if the ground is slippery and wet. Just bock in areas where the ground is not wet and slippery. You want dry ground to bock on so that is the most important thing. Alot of us bock in the winter too, I actually learned to bock in the winter time.

Just dress warm 

Ya being 8 feet tall rocks. I remember when I first put mine one lol, oh what wonderful memories
