You could replace Deadlifts and Shrugs with Cleans, yes. In part at least, giving a transition period, if needed. Upright Rows may help during this period. I would also use some Shoulder Presses, as time goes by (e.g., as a progression/alternative to Flies). It would be good to consider Reverse Leg Press, Hypers, etc, too.
I like deads so I wouldnt drop them.
I do mine in this order
Cleans, Bench, squat
Or
Cleans, bench, dead
would the sholder presses be more draining on the CNS compared to the flies? or does it not really matter too much at this point of training?
Don’t worry about it! 
would you reccommend i do full body weights twice a week or split it as i have? im thinking on the grounds of CNS recovery but is that such a factor during this period of training ?
excellent 
Also what would you guys say are realisitic targets to set myself for next season over the 60, 100 and 200 ? If I should even set them at all? do you think a sub 11 is ever possible not for next year but lets say by the end of u23?
it depends on u. If you think you can handle it go for it. If not then split them. Im am about to start splitting mine.
Hmmm I think I’ll keep mine as a split i find it really takes it out of me if i really rack up the volume in the gym.
today i done back to back 60ms 4 sets of 4 recovery 30 secs,25,20then 2, 3 , 4 mins between sets. wirked up quite a sweat but not too difficult.
spoke to my coach today training offically starts on the 2nd of october (GPP). Until then just doing some stuff to build an aerobic base.
today done 6x 300 with 4 minutes rest, i must say it was quite a struggle, serious jelly legs and form breaking down in the last 100m !
gym
cleans 5x 60kg 5x65kg 5x65kg
bench 3x10 75kg,80kg new p.b 75kg
seated rows on cable machine 3x10
today we started our GPP. We had hills runs.
warmup up with drills. 5 reps today, trying to increase a rep every week i tihnk the eventual goal is 10 runs. the hill is about 50- 60m in total.
this was painful. lactic acid at the end ! i forgot what that felt like lol.
its been a while since i updated my journal but to bring you up to date. on the 3rd of december i ran in the south of england student championships for 60m and ran a p.b of 7.3 and in my heat i ran 7.4. last year when i run this comp i ran 7.5 so im very happy with my results ! my first proper indoor race will be london indoor games on the 29th and 30th on january. followed by the essex indoor championships the weekend after. both of these i will be doubling up ( 60m and 200m).
my 6 week training block consists of change of pace stuff over 60m, blocks, some speed/ speed endurance e.g. 60,80,100,120 and 1x60m,2x200m,1x60m.
ok so yesterday was my first offical race of my indoor season. my first race i false started which really messed up my reaction and i got left in the blocks. i ran 7.42. in the 2nd round i got out better but still not happy with my first 20m. i ran 7.37.
from viewing over my race in december, two races yesterday and training videos, it appears i am losing alot of ground in the first 20m and then my top speed seems to be bring me through at the end. so starting power is an issue for me.
today i ran the 200m at my indoor county championships where i came 3rd in a time of 23.91. im not sure how to take this as my 200m p.b is 23.47. this is my first 200m of the indoor season. last year outdoor i opened up in april with 24.1 so i guess this isnt too bad but still disapointed that i am 0.44 off my p.b 
hopefully the 60m tomorrow will bring more dividends
Most people run around 0.3-0.6s slower indoors compared to outdoors.
My outdoor pb is 21.99. My indoor pb that year was 23.1x. Hard to gauge your outdoor time with an indoor one, just keep progressing!
All depends how that second curve throw you off.
