Not another board length question

Hi,

I'm a beginner/intermediate snowboarder, have about 10 days under my
belt. I learned to ride in Hunter Mtn. in NY when I was interning
there last season.

I have an opportunity to buy Burton Feelgood, but torn between 144 and
148. I'll be riding the board in Colorado this season, but in New
Zealand after that (i.e. can get real icy here!)

I'm 5' tall and 110 lb (fluctuating wildly). I learned on Burton
Cruzer 140, but did fine on 145 (I didn't know that I was riding
longer board - I only noticed it after I had a great day on it!) and
thought Burton Feather 147 was too soft.

Cheers,

Serena

(Hmmm... I could buy both and sell the other one in New Zealand)
