You don't have to go durring the TTAC3 events if you want. PM Brian and find out his schedule. I went through Brian also and went on an off day for airsoft so you could probably just stop by after school one day. Was a great opportunity to also talk to him about questions I've had about airsoft. He is knowledgeable and is a good guy.
When I went to a TTAC3 event as a newb I picked up so many things about airsoft it was so hard to process all of it at once. The people I met at TTAC are pretty cool and knowledgeable about a lot of guns, gear, and anything under the airsoft category.
If you don't get AV through him there are other West end Toronto AV'ers and I'm sure they will be more than willing enough to help answer some of your questions you've got.
