bet spread / ROR question

After months of practice I plan my first casino visit as advantage player. The casino I chose has the following conditions:

6D, S17, DOA, DAS, RS4, ES10, ENHC, 75% pen

I know this is not great, but its the best I can get.

My trip bankroll will be 50 units. I plan to backcount and I will only play at a TC of +2. My spread will be:

+2: 1 unit
+3: 2 units
+4: 3 units
+5: 4 units
+6 and above: 5 units

I know I will not get heat at this place, since I probably am the first counter to ever set foot in it. The tables are crowded with backbettors, I will be just another face in the crowd.

What do you experts think about this as a first aproach? Also, what will be my risk of ruin and how would it change if I play all and bet 0.5 units on all counts below +2?
I count hi-lo and know 25+ indices

This question can't be answered until you decide on a goal, but if your goal is to double your trip stakes than your chances of winning are 61.40 percent.

Good Luck

Does this mean chances are 61.4 percent that I will reach this goal, or that I will walk away a winner? Also, what are the chances of loosing part of or my entire trip BR?

You have a 61.4% chance of doubling your BR before losing it.

--Also, what are the chances of loosing part of or my entire trip BR?-
You have to be more specific than "part", but your chances of losing the entire trip stakes are 38.6%.
