Hey Goldman,
Can't argue with Mac's comment you can't really go past a Mc Tavish.
If you are after a HP longboard have you also checked out Laguna Bay's super model.
( MSJ Model )
I just got rid of one of these and can say they are the shiz.

Massive rocker, heaps of concave and light


The only downfall IMO is the deck can get bumpy, But I am 120 Kg's

but at 75 Kg's you should be ok.
