6max o FR?? To be honest I think the most important preflop stat is PFR not VPIP or flops seen%. If you can also determine a villains raise calling range, most of the tight players are all very similar, you will be able to narrow down your opponents holdings very quickly. By calling with the connector type hands you make it hard for your opponents to read you, and those str8s are set killers. This is why you are making money, however you probably still have a ton of leaks playing this loose. I think you are playing to many trap/weak type hands (KTo, J9o??). You need to find a medium where as you are tight but hard to read...
