br suggestions

any suggestions as to bet spread and br for a 6 deck game das doa s17 i use hi opt1 .i can honestly add maybe 150$from my job per week to replinish my br.because actually i am beginning with short br ,thats why i asked about the lifetime session and playing with money from job on weekly basis.these games around here are 5$mins where as the dd games are 25 mins so im assuming being short rolled i would be better off on these shoes?
