*Waves* sorry yes I have a Wee Hoo, currently in manic mode where with moving and stuffs...
I have never toured (yet) ha ha ha but I do use it almost everyday, I have a 4 y/O and got it about a year ago I have the I-Go Pro. I can say Wee Hoo Jeff in the States is marvellous, I even got the All Weather Canopy before it was available for sale in the UK when we had all that wet weather in January/February and I was running out of dry waterproofs, I begged him to send me one. We love, love, love it. She also has her own bike and rides that too, but for longer journeys, tired journeys or ones that are on busy roads (we have one of the busiest B roads in the country we have to use to get any where out of the village) we use it.
Also User76 can fall asleep in it, which was a god send when she started school as she was so tired by the end of the day, and she is safe.
When my eldest was 8 he fitted in it comfortably... now he is nine and had a growth spurt it is not so good for him (plus he is heavy when he decides to be lazy and not pedal and it is rarely he gets in it). You feel the assistance even when a 3 year old is pedalling!
I would say wait for the new one, the changes look fab (especially seat adjustment/pedal straps/clearance) and I would say go for the all weather canopy rather than the sun canopy it is more use they both are easy on easy off...
