How hard is this cable pull?

I have a 38 FT run of 2-1/2 IMC from my disconnect outside to my first enclosure inside the building.
It has (3) standard radius 90s and (1) 30 for a total of 300 degrees of bend.
This is a 200A 3P High leg Delta installation.
The pull consists of:
(4) 3/0 conductors, 3P + Neutral
(1) #4 EGC
For referencce from the fill chart I am allowed (7) 3/0 conductors in 2-1/2 IMC.
From your guys experience how hard will this pull be to be done by hand?
Big thanks
 
Shouldn't be a problem by hand if you can make a nice staggered nose and have several guys pulling. The details matter too like how easy is it to feed, can it pulled out straight, etc.

Are any of the 90’s back to back or staggered throughout the 38’ run?
 
The 90s are spread out as shown in green.
I could put an LB/SLB to the side of the outdoor enclosure because it's narrow, but I'd rather not.
Worst case I could make the pull with the outside enclosure off and then feed the box over after.

Normally, it's better pull from higher to lower, but your ends strongly suggest pulling up.

The most valuable advice I can give you is to have at least two people combing and feeding.

If you can leave off the outside enclosure, leave off the elbow, too, and pull down.

Still have the two feeders. (people, not wire)

But it's still a DIY project then. Do your self a favor and let a EC assist you we with this. Even though it's not a big deal to us who do (or did) this type of work it could be a nightmare for the inexperienced.

Not new to this. Just haven't pulled 3/0. I'll have two people on each end.
 
I really appreciate all the input. You guys rock. I figure spend the money on the 2-1/2 versus 2 in.
How bad it could it be right. I'll get back to you on that one.

You could shrink the ground and neutral, might save some $$
If its a 200A feeder you only need a #6 EGC
And I have reduced the neutral to a #1/0 but some don't approve of that an prefer a full size as many 240V deltas are eventually converted to a 208 or I am not sure why really, some 240 feeders I have omitted the neutral as there was no neutral load.
I am not sure what the rules are on the neutrals, but I am fairly sure on a 200A feeder #6 CU is allowed.
 
It should be extremely easy. Unless all uphill, you will probably find your guys may be able to push most of it in.
