Alright - in need of some advice.

As a total non skater (but competent windsurfer/SUPer - so some sense of balance) who is looking to keep up with his 4 year old on a scooter, and have another winter fitness option.

Can people point me in the right direction for a good longboard?

I have only just started looking and I seem to have established that bigger is better, low to the ground is better. I don't have any real restrictions so far as portability concerns go, and am willing to look at the whole range of budget options from small $ to big $.

The G-Bombs look like an interesting idea, what do people think of this as a place to start - I'm guessing the push model? or should i look at push-pump as a way to progress? Otherwise - I've heard Tan Tien Flex, or Sector 9

What about street SUP - should I be going in that direction?
