M-chest/tris
T-back/bis
W-shoulders/legs
T-rest
F-repeat
X2 a week

That's not a split. That's just listing muscles. A split is volume, rep range(s), progression, etc.

I would not advocate doing shoulders and legs together. Hit legs alone. I also don't like doing tris with chest, just my preference though.

I am not a fan of chest/tris and back/bis either
You really should look into Eric Broser's Power, Rep Range, Shock training. It' dhelp you build a better split with exercise suggestions and gives specific rep ranges, sets, etc... that change each week.

Why don't any of you like the split? Can you recommend me one instead?
Also I am natty if that matters
I'm doing
back/tri
chest/bi
shoulder/legs
I do a 10-8-6-15 rep range (vince gironda technique)
and i have 2 full body power days
I have a part A routine which consits of supersets and part B which consists of tri sets, mainly volume training, doesn't matter what body parts you work together or what you do, I'm pretty sure some top bodybuilders have used the split you want to do, it's all about technique and nutrition,just gotta find what works best for you
although i recommend you rest wednesday or do cardio, also rest friday, and for other days do something different,than repeat monday using a different technique,switch it up and make sure your getting everything you need in your diet
This is Gunter Schlierkamps off season. Try it out its pretty good. Got it out of musclemag.
The problem is I'm trying to hit each muscke group x2 a week or close to it
That is a lot. How come you want to do each one twice a week.
You could always find a good upper body workout and a good lower body workout. Then split it up like:
Monday: upper
Tuesday: lower
Wensday: rest
Thursday: upper
Friday: lower
Then whatever you want on saturday and sunday.
