help on routine

Ok, well im wanting to put on as much mass as possible. Ive got my diet down, supps and all that stuff, but my rountine is questionable.

Monday-tri's
Tuesday-Back
Wednesday-Bi's
Thurs-Legs/shoulders
Friday-Chest
I do abbs like every other day.

I do one bodypart a day because i think it just makes since that i can hit that certain body part harder than if i do 2 bodyparts, but i mean i could be wrong, im open for suggestions. I do about 4 sets of everything, 10x8x6x4.
Is there some other workout i should do to gain mass, i am really going to concentrate hard on everything i do this time, 100% on everything,because im wanting to gain weight. I am going to log everything down and all that good stuff, but i need to get everything strait before i go into this, so any help would be apprecaited, thanks in advance.

I'm sorry bro, but I've never liked the 12,8,6,4 routine. I work out at MetRx in Newport Beach along side some of the biggest pigs on the planet and they never use it. I have seen more beasts stick to 1 workset than any other type of routine. example

Chest-
Incline press: 15 reps warmup, 15 reps warmup, 12 reps warmup, 4-6 reps work set

I work set per muscle up to 2x/week.

like follows
Monday- chest,shoulders,tri's,back(width),back(thickness),calves

wednesday- quads, hams, biceps, abs, forearms

Friday- same as monday

that would be your week. once you step up to the next level just split it up to Mon,Tues...Thurs,Friday

The next week you would do Wednesdays routine on Monday

ok, exactly why i posted what i wanted to do up here so i can get other opinions. And i didnt think doin sets of 10x8x6x4 was high frewquency? Thats why i said i am open to suggestions.

I see little results, but i was wondering if there is something that would work better?
