should I increase unit bets in this case?

I don't know if my local bookie is idiot or he thinks I am too dumb to win at betting football. A lot of times he offered me a good deal but I don't know if I should increase my unit bets.

For instance, I told him that I like Team A but the line has jumed from A (-10) to A(-12). He said back to me that he can let me pick A (-10) instead of A (-12). If my normal bet is 1 unit, do you think it is a good chance to increase my unit bets?

Only if you are up in your bankroll for the season or overall. Or if you feel a nice edge (More solid reasoning) on the wager.
