Forearm&Bi lagging in CGBP, and what powers skull at the top?

[Milhouse Van Houten]

hello, I have been using the recommanded Tricep work out for 6 months, and disregarding my bi since i was training at night.

I am 5'11, 185 lb with 14 inch arm, cold and unflexed, I am currently close grip benching 100 lb with somewhat shakely movement ( it has been improving since I started training forearms).my tri can support a 6 reps (20-25 seconds) set easily. ( i stop at both top and bottom)

i have been training bi for past 6 weeks.

questions 1) how strong bi has to be to power 150 lb CGCP, i am currently EZ curling 40 lb x 8, cant straigt bar due to weak forearm.

2) how bad could the shakely movement affect my tri's mass building? or should I drop back to 90-95? or even increase the pushing speed?

3) i know this is sad, my skull has been stuck on 40-50 lb for long time, and would a strong forearm help out here? Also, what powers the skull at the top of a rep? i have been using for wrists quite a bit, should I lower the weight?

4) what is the proper width on a straight bar when training foreamrs?

Thank you.
