I pulled the Kyosho Blizzard with our new Sherman and totally owned it
If you take a look at BigSquidRC.com and look around for Adam "The Intern's" 8x8 you will see the monster. I'll look around myself as well... I swear I took a ton of pictures of it somewhere...
However, his 8x8 is a MONSTER beast and totally owned the Sherman. The weight on it is a lot and those soft rubber tires have a lot of grip. I switched over to the King Tiger and just barely couldnt pull him. It was hopping trying to pull it but it just couldn't compete with those rubber tires on the carpet. Next year with our metal track/rubber pad grip combo on a certain new tank it should be a bit different
Hopefully there is a 2015 iHobby show next year to compete! I'm sure I'll see them before this time next year anyways, RCX is a large show and definitely my favorite show of the year. I even got gourmet beef jerky at the last RCX show
