"any suggestions as to bet spread and br for a 6 deck game das doa s17 i use hi opt1 ."
Hi-opt 1 not a good count for 6decks. Change to hilo. You must because the time to master hilo will be compensated by the waste of time you use hi-opt1 even in a few months.
"i can honestly add maybe 150$from my job per week to replinish my br.because actually i am beginning with short br ,thats why i asked about the lifetime session and playing with money from job on weekly basis."
How often and long you plan to play each week? What is your initial br? You start with your initial br and find a risk level that you're comfortable with losing it, to derive a betting scheme. Then increase your initial br by $150 per week hence your bet size will increase by 150/initial br.
"these games around here are 5$mins where as the dd games are 25 mins so im assuming being short rolled i would be better off on these shoes?"
6decks have much higher variance than dd. Hence enter at your own risk. Besides the edge is lower also, and it takes much more stamina, not recommended for beginners. I suggest you table leap or just stick to DD.
Tell us your initial br and what kind of risk you can live with.
