For runstops I use LK+HK (though LK+MK also works). You don't want to use LP+LK because this is 1f slower than doing it with 2 kick buttons (don't ask me why). Sure, it ain't much but anything to make those run stop links easier.
I'm assuming everything above the combo are the resets you want to learn. Just some notes:
-For the first reset: cr.LK, cr.MK, RS, airgrab/j.HP. Don't use j.HP unless it is in the corner because you get nothing off of it as it will just toss them away. The reason you would use j.HP instead of airgrab is to catch the tech attempt, instead use LK, MP. This keeps you grounded and sets up a land cancel reset opportunity if they block (LK, MP, MGR) and leads into a full combo if it hits since you can hitconfirm after the LK, MP. You can also do left right mixups from this setup by either doing cr.LK or dash cr.LK (cr.MP on Band and this won't crossunder vs Double).
-What is the second reset supposed to be? If you are trying to setup a left right from your launcher using bypass then this isn't a good mixup because bypass has very little range. This sort of setup works with tall assists as they are forced to block the left right and guess + whatever mixup you do on the ground.
-The third one is a reset with pummel horse? If so, don't reset with pummel horse, if it is blocked then you are punishable for ages. Instead do RS, cr.LK/Cmd throw/instant j.HP/kanchou. This is much safer (apart from kanchou) and gives you more options.
-For a midscreen combo this is the best one I know of:
If you add a titan knuckle on the end then it does 8.8k which is crazy and if you finish in the corner you can either do another dynamo or battle butt (more damage than TK) or cr.HK, Battle butt/RS (battle butt/RS will armour through any burst giving you a mixup). This combo is pretty hard if you aren't used to run stop links though, so a combo that you could do to work up to it is: cr.LK, cr.MP, HP, Kanchou, cr.MK, j.MP, j.HK, HP, PH, cr.MP, cr.HP, j.LPxN, j.HP, cr.LK, cr.MP, HK, Cerecopter, Dynamo. This one doesn't have any run stop links but still teaches you to use kanchou and pummel horse. I don't know what damage it does but it should be pretty good. Once you learn run stop links you can transition to the full combo. It is important for this combo that you input kanchou as <-, -> MK+HK as otherwise you the kanchou can be blocked vs Band (because he's fat). Vs double you have to do dash, cr.MK or it will whiff (this is quite tight so you might want to learn either a Double specific bnb or just use your normal bnb vs her).
