About length routine

Basically as far as I got it - there is plain stretches, s2s, bundle stretches. And that's it?
I figured out I have no idea what I'm doing now with stretches without jelqs or anything else. I'm on my way getting my devices but till then I can only stick to these three?

My length is 6.25 and my girth 5.25, length is my focus now, to get an 8''.

What do you guys do with manuals? Did you form your own routine? I've seen DLD's stretching routine that is basic jelqs+stretches, that's it, also bundle stretches at the beginning. Big AL's too, only s2s and holds..

So far only routine I had experience with are JP90 and LPSG(where LPSG and one from thuns(newbie routine) looks like low volume ones)

What do you think?
Any pin points on duration of each - for example 15 min stretches all sides, then 3x50 s2s, what about bundles?
Thanks

Bundled stretching can be very intense so you should start off with some basic stretching or s2s for a while before attempting it. If you scroll down in the Penis Exercises link at the top of the page you will find a list of several other advanced stretching exercises you could try later on when you are conditioned enough for it.

you can gain with just stretches into all directions. increasing intensity and/or time until you see progress/gain.

Start with the least intense methods of stretching first. Build up in reps and force over time. Once the exercise fails to yield more results, upgrade to a more intense movement.

There should be no need to perform multiple length movements. One or at most two length exercises in a session should be plenty.

Its very easy to want to do multiple exercises to maximize length but truth is you can just do stretches and s2s and it be effective or stretches and bundled stretches.
