So been thinking about how to should proceed in deep stack NL preflop vs. competent lags/tags facing raises OOP. I'm thinking like 250bb+ deep situations in 6max/FR games. This is decently common in live games. If competent player opens IP this deep what type of 3b range are we trying to have here.

If we 3b value only (TT+,AK) we will get bent over backwards post due to being extremely capped post on most flops and OOP. But if we go wide we are now playing wide ranges OOP with very little fold equity preflop due to implied odds. Which obviously sucks.

Seems then like at a certain depth we should no longer 3b and simply play our hand under repped or start 3bing very wide/balanced (i hate this though because i don't want to play big pots OOP). Maybe I am overvaluing position but the deeper we get the less i think preflop value matters and the more position does. What type of range are you guys trying to use in these spots? Am i crazy for thinking that flatting whole range instead of 3bing could be more profitable?
