@Ansel Welcome to FC!
I was in the exact position as you, got a PNP originally and found it wouldn't get me high enough. The solo is definitely a little better than the PNP in terms of taste and extraction. However, if you like me were smoking a lot of joints before you went to vaping, the slow warm up time means you can't get high enough quick enough.
What you need to do, is bring out the big guns.
First, go over to this web page and learn to understand this well:

These pages give you the know how to make high quality cannabis concentrates, like wax and shatter.
Then, buy yourself a Persei, a matching SS kit, an XTAR VP1 charger, 4 x AW 18350 batteries and 4 x 3.7v ti gr2 kiss carts. This will give you a tiny pen vape, about the length of a pair of small manicure scissors that will give you the ability to get higher than any joint could ever get you and do so in 10-20 seconds no less!
I am not exaggerating. One battery will last all day generally, but the batteries are user replacable and tiny.
Bring this out with you and vape QWISO wax/shatter instead. It will be super cheap to make, taste fantastic and once you've learned to make it a couple of times, you'll be producing shatter in half an hour flat
