Hi @
cosmonaut! I don't own a J-hook yet but using some common logic drives me to the following facts:
1) The straight stem is preferable if you need to hold it in your pocket or small pouch (Ryot case in my case...

) as it won't break accidentally.
2) The J-hook will give you cooler hits, less debris in your mouth (cause of the curvature) and more style...

3) The J-hook will mandate that you use the WA, which has a better airflow (bigger hole under the screen) and I have found to avoid charring easier when using it...
4) The straight stem, especially the long one, can be used very effectively for self defense as you can stab someone very effectively!

5) The J-hook though, if broken can also stab someone but you will be left without a pipe...
As for comparing the Lotus to the Solo:
1) The Solo has zero learning curve so sharing it with friends who never used it before is easier.
2) The Lotus offers more freedom. I wouldn't go for an outdoor adventure for more than a couple of days with the Solo...
3) The Lotus will give you faster sessions. Go for a pee in the toilet and have a Lotus session in less than 2 minutes is as easy as 1-2-3.
4) Due to the possible shorter sessions Lotus can be gentler to your throat and teeth as they are exposed to high temps for shorter periods. Not so sure if you care about that though due to your use frequency (for better or worst vaping will most probably drive you to use cannabis more. It is so much more enjoying than smoking that it can get you there. If you have the herbs then it's great!)
5) The Solo might be a better choice if your herbs are not of so good quality and can't handle high temps. Lotus will char a week flower easier than the Solo. Needs some careful flame usage there...
6) With good herbs Lotus for me is just a better overall experience. Faster, bigger hits an lots of style!!! More durable too!!!
Feel free to ask anything else! I hope I covered some holes...
