Utilizing more stats on my HUD

Right now all im using is PFR/VPIP/AF/handsplayed to make decisions about players. Over a couple hundred hands if i noticed their PFR is high then im more apt to raise them with position on their blinds, or if their PFR is high im more apt to 3 bet them. However I know I must be missing out on some juicy goodness with all the extra stats im overlooking. I think the fact that all the numbers and such intimidate me and I dont want to bother learning the effects of all them. Went to SD, won $ at SD, i think those would give me some extra ammunition at the tables if i could understand what the numbers mean. I understand their definition, i just dont understand how they translate into me playing againts the player better.

WTSD% is pretty useful to but I have the same stats up as you.

Aggression by street is pretty useful.

I also like folds to continuation bet and calls raise preflop/cold calls preflop.

Blind steal numbers are OK, but I usually leave them on the popup rather than always displayed.

i use those as well as C-bet % and W$atSD%

I use the same ones as you, but mostly because I haven't figured out how to change them yet :?

Side question: Am I losing value by only using Gametime+? It seems limited compared to pay-for HUDs but is it really worth it to upgrade?

i used Gametime + for a while, and since switching i cant say for sure that PAHUD has increased my winrate, but the extra info on the screen does help.
