Last min. AC reccomendations before I pull the trigger

[Awjunkies]

72 K10 suburban with factory front and rear AC.
Swapped in a 5.3 4L80e combo and have a sanden type compressor ready to go.

When I bought it the previous owner said he had the system recharged 2-3 times and it worked for about a week then didn't so it has a obvious leak but he didn't know from where.

I kind of hate all the bulky mess of the original AC setup so I planned to get a vintage air/classic air, etc...

Reading through years of threads Vintage Air genIV surefit seems to be the best performing however only for the front driver/pass. Some people reccomend getting the slimline for the rear whereas other people have said that VA also makes a monster cooler but it's not a sure fit system.

Any reccomendations before I pull the trigger?

I haven't had the stock rear AC tested so I don't know if the leak is there. The fan does work and it has the lines all hooked up.
