fr utg range question

[rong]

So I normally open something like:

77+, AQs, AK. 68 combos.

If I'm 3b, villain dependent of course, I prob continue with:

TT+, AK. 42 combos.

So basically 77-99 and AQs get folded.

So am I better off scrapping say the low pps and replacing them with say AXs?

If so, what table dynamics would make one range preferable to the other?

Or... does this not really matter.
