Got single 60GH about 2 mon ago, got my ROI back and plus about 2 btc profit, with in the last 2 months my single found 2 blocks. I am thinking of going solo, please advice

If I keep mining with the pool, ATM my average btc per month will be around 1.7 btc and of course it will be lower  with the dif increase, should I go solo ?
