I think everyone is out riding!
At ur weight you could ride a 134 but if you want ur dad to ride it as well then(depending on how big he is!) you might need a 137.
as for board depends on budget.
Hyperlite motive is a great all round board.
Liquid force litmus was a good starter board but i dont think they make em any more
Have a look on here
