yeh im 196cm (6’6) 220 pounds and have fucking long limbs
at 196cm tall my arm span is 210cm and sitting down im the same height as my old man who is only 5’10 lol
so my arms and legs are way behind my torso in regards to ‘looking’ big
my foreams are pretty decent, upper arms not to bad, quads and hams bad, and calves absolutely pathetic
so these are hard points for me, but i think they will come good its just a matter of time as ironmaniac said adding the mass to look bigger which unfortunately takes so much longer for us
although on the flip side i have wide shoulders and extreamly thick chest and back for my weight, people think im bigger than i am because of my pecs then they look at my arms and have second thoughts, or they ask me how much i bench and i sigh and tell them to ask me how much i deadlift instead 
as far as exercises go im with RommelKorps u gotta do the big compound lifts for the reasons he mentioned
i live off bench, squats, deads, cleans, presses, chins, rows and dips
then i throw in the extra isolated work for arms calves and legs
even though i can just do 5 reps ATG squats with 220 pounds i gotta keep doin em cause i dont wanna have those shit numbers any longer
my bench as i said is shit 1RM is 220
but i can strangely do DB flyes for reps with 60 pounds which i think is decent lol
but the lever disadvantage for bench and squats does wonders for rows chins and dips, at least for me
deadlifts are my best 1RM of 500 pounds and 5x400.
as for advice i think its vital for us talls to work your core alot as ive only recently discovered, it has made such a huge differnce to my lifts in only a short time and i mean core stability not crunches and shit, im at T-Nation so u guys all ready know this.
also i highly recommend getting checked out by a body specialist of some sort to get an analysis of strength tension relationships, imbalances and weaknesses in your muscles as i think tall people are more likly to have problems with glute activation, shitty hip flexors lumbar spine and other shit lifters dont want.
a few sessions with a guy who knows what he’s talking about and following the exercises he gave me fixed my posture, nagging pains and i made steady progress on major lifts involving legs and core
