Zenyatta Ventures Ltd

I have a $30,000 line of credit with an interest rate of 5%. Right now my LOC has a 0 balance. My question is: I could add up to 15000 more shares to my holdings - so would you use all or some of it to buy ZEN stocks now and pay the interest for the next while? Or would you wait for a while to buy? Or would you buy at all?
