I have purchased all the material you mentioned in your post. All the courses are good guides to get started in PLO. All the material mentioned are all solver based, so there is some over lap. All the courses have a slight differences on strategy.
As EMTY has a no cold calling or completing the SB preflop. So I think his SB preflop opening frequencies are different from the other courses.

I would stick with FTGU course, because of the videos on facing multiple players, postflop and preflop. Plus EMTY explains on how to start thinking about your range and your opponents range etc.

The only negative thing I can say about FTGU is the solver charts and graphs are hard to see.

The Upswing Launch pad is very basic ( its a 100 bucks ) so you get what you paid for It explains preflop okay. Post flop you get all the what kind of boards paired , straight, monotone etc. Also what kind of bet sizing to use on what board.

Just started to read Fernando's book, going through the prelfop chapters explains the types of hand categories in detail..

Thank you for your answer, as from the staff here nobody seems to be interested in this forum, not even the creator of the course (don't know if he sill works for RIO).

That sounds not fine, als I suspect, that the solver charts and graphs are the main part of nearly every video, am I right? If so I probably will not get the course and search elsewhere, as I'm not interested in a course, where most of the information is nearly not readable (even not on a big monitor).

According the Launchepad: Yes you are right. I got it with a 25% discount, so it was okish, but it really seems mostly to be just a PR-thing for their expensive course and there is nothing in-between there. So tbh.: Not sure what to do. I rather don't want to invest that big (especially because I was not convinced on the Launch Pad and I'm even not sure if the step is too big for me) and it seems you nearly have buy the pokermatrix too, if you want to take the most out of the more expensive course, am I right?

Sucks somehow...

Is alternatively thougt about 2.3 months of essential membership (i think i have one open from when i bought Pete Clarkes Course, and watch some Videos of the learning paths, but most of the vids are rather elite or many years old.... hmmmm...

I would like to have the solver charts visible, but I don't think its that important. The course came with some PDF files with some charts that have percentages on what type of boards to bet etc. These charts will help you understand the GTO theory

I was also thinking of signing up for essential membership, but I just don't have the luxury of watching training videos all time.
That's why I decided to go with From the Ground up PLO. At least I can take my time and go through the course.

I haven't finished the course yet, but it has helped my post flop game a lot. Post flop has been the weakest part of my game. Now I have a decent understanding on how ranges and blockers work.

Good luck on your journey Bro.
