SS table selection question

[JH1]

I've noticed that in the evenings (and other parts of the day, but especially evenings) there are quite a few 6 max tables that have everyone sitting with 40-60 BB. I normally try to sit at tables with as many full stacks as possible.

I've read some 2+2ers comment on how people that are not very good usually buy in for the 'recommended' amount instead of buying in full, so I was wondering if these tables could be more profitable if I pick my spots and tighten up a bit considering I don't have the implied odds that I do at full stacked tables.
