Better sessions

Ahoy hoy!

For 4/20 I got a great deal on an arizer XQ2 an was excited to try it out but after 5 sessions I feel like I'm doin somthin wrong as Im getting a lil vapor an some taste but thas about it. Last 2 bowls I used the larger bowl filled at half way, because it's closer to the heat, I'm preheatin for 5-20 minutes, and am startin at 450f, an still is not givin much. I'm not expectin big ol vape juice clouds, but I get more out of my 501 cartridges an the high is not on the same level, any suggestions?
