Learning vs RFI ranges with GTOw

I learned some RFI ranges from GTOw, now I am working on learning the vs RFI ranges. The games I play are 8max, so I use the GTOw 6max ranges for LJ to BTN, and the 9max NL50 rake ranges for UTG and UTG+1 (UTG+1 and UTG+2 in the 9max ranges).

The problem is they seem really tight. For instance, 8handed UTG+1 3bets 6.2% of the time vs an UTG open. This includes folding JJ 68% of the time. 8handed LJ 3bets 7.1% vs UTG+1, folding JJ 32% of the time.

I plan to spend a lot of time learning ranges and just want to make sure I get on a decent path. I've already messed up before by learning 300bb depth ranges, and had to relearn haha.
For 8max:
UTG - GTOw 9max 50nl UTG+1
UTG+1 - GTOw 9max 50nl UTG+2
LJ to BTN - GTOw 6max LJ to BTN

Are these good 3betting ranges? Thank you for any feedback or advice.
