Well, all the guys so far have steered you in the perfect direction, so I'm only going to chime in with a +1, if for no other reason than to have one more person telling you to change ALOT with your current diet, training routine, and the way you think/take AAS
While it sounds like you're absorbing what we're all telling you, it seems you're more concerned with answers on how to run your cycle, when that's the least of your worries! The simple answer to that question: yes, 10 weeks is plenty; yes, pin only twice a week with enanthate and deca, 1ml each twice a week; if you adjust your diet and workout routine, YES, you WILL STILL GROW, guaranteed... doing more AAS, or more frequently than the "last 2 times you did it", which you seem fond of not letting go, is not gonna make you bigger...
If you cut out alot of that processed, fried, and starchy food, and those awful weight gainer shakes, and replace with things like oatmeal, BAKED sweet potatoes, brown rice, whole wheat pastas & bread... and eat more GRILLED meats like chicken, turkey, even lean red meat... YOU WILL GROW... I think Tom said it... figure out your caloric intake presently, have someone help you calculate what YOUR BODY needs to grow, and then start eating accordingly.
Definitely combine your arm routine and take the extra day off... 2 days off is better... your body grows when you rest.
One last thing.... if you finished your last cycle at end of May, that means you're only given yourself 2 months to recover...definitely not enough time off.. I've always like the rule of time off = time on + PCT... so if your cycle was 10 weeks, and PCT is typically 4-6 weeks, then you'd have a time off of about 4 months... let your body recover fully, otherwise your next cycle will be largely wasted... you want your body primed and fresh for the next cycle.
Good luck!
