Yep I'm onto to wide fork. Be nice not to spend that money if not needed. I have bought it for a rough strip plane. A bit of speed does not concern me. Of course weight does. The Cart tyres seem very light. So maybe spend the 250 or so on the fork and axle. Then three cart tyres and carry a spare tube. I have three in the kit I'm not using nd I'm sure will work in a bind.
