Of course raising a smaller % of your
hands will polarize your range to an extent, assuming you're not literally randomly raising every 20th hand your dealt. Live games are interesting though, you can be playing a really solid game but give off the impression you're playing just as loosely as anyone else, a lot comes down to your demeanor. If you're sitting there wearing a hoodie, listening to music, not talking to anyone or making eye contact, you're going to likely come across as someone just there to make money/exploit the more recreational players. Make the games fun, talk to people, it makes it so much more enjoyable for yourself and the recreational players who you want to have fun regardless of whether they win or lose.
If you're engaging the other players, especially if they're recreational, they most likely aren't going to notice if you're playing 10% of your hands or 35%, just keep it fun.
As far as what % of your hands you actually should be playing, that all depends on you and the players at your table. If you notice someone playing super loose pre but playing extremely fit or fold post then get in there with them with a wide range of hands. If there's one of the aforementioned regs with the hoodie and headphones just grinding away playing a tough game, tighten your range considerably against that player. It's a tough question to answer that all comes down to specific table dynamics.
