Always remember that the arm muscles (triceps and Biceps) are small muscles and are easy to overtrain. Train them really intense with lower sets (5-7) for each muscle group in the arm and see what happens. Remember, you use your arms on all pressing and pulling movements.
I'm with you on that working the bis twice a week is too much but I don't think working bis after back is uselss. For the past couple weeks I've worked my bis after back and tris after chest with 5 days between same bodyparts and have had great results. Just my experience.
Lay your foundation first. Hit compound movements that use your arms as secondary muscles. Bench press, barbell rows, dips, chins, pull ups, etc... Big arms are made over time...lots of time.
Remember that the tricep makes up the majority of the arm size anyway...so blast them in a big way.
What is your age, body weight, measurements, etc...
My arms look a little thin (to me) but they are very very long.
Do one Exercise for biceps once a week with a weight you can only do 6 times for 3 sets. Add weight every week. Added strength = added muscle. For example:
Week 1 Standing BB curl 75lbs
Week 2 80lbs
Week 3 85lbs
Week 4 90lbs
Week 5 95lbs
Week 6 100lbs
Once I added direct grip training and forearm work twice a week, I put noticeable mass on my bi's in a (relatively) short time just by sticking to compound exercises. I'm not sure why that is, but they were obviously a weak link in the chain.

I really don't want big 20''arms, a solid 16'' would be great. The rest of my body I am very happy with and don't really want much more growth but more ripped, maybe a smaller chest. My chest looks to big on my body frame, especially with my small arms.
also my arms are very long, thats part of the problem, but something I can't change.
Long arms are good for a lot. They look really big...when they get really big.
I hate to tell you this, but I believe that the rest of your body will have to get bigger before your arms will catch up. I know, it does not make any sense...but it is a general observation. You don't see many guys with 20" arms and small everywhere else.
