Pay to Play, Yay or Nay?

So lately I have had some pain points around our regular Saturday night gaming group, and have been kinda passively looking around at some possible alternatives. I don't really want to go into what the pain points are here, suffice to say I love my friends but I have not been getting a lot of satisfaction out of the games lately. Also, I really, really, really want to play Shady. Like, she's the only character I truly want to play, playing other characters when I want to be playing her low-key makes me sad, and the chances of getting to play her again in the current setup are, well, slim.

Today I happened upon a game on Startplaying.Games (the site that manages my Sunday night professional games) that, with the exception of being 5E instead of PF2E, really sounds like it hits all the right notes: RP-centric, pirate-themed, lore-heavy, backstory and plot tied directly to the PCs, heavy on the swashbuckling romance. It appears to be scheduled to run on alternating Saturday nights, with the first session being while I'm away at MFF (so I couldn't make that one), but the GM says I could start with the second session without it being a problem.

So now the question is... do I do it? >.>

My two big hesitations are a) disrupting the Saturday night group, and b) the cost. On the latter front I'm a professional GM myself, and the price is completely reasonable for the amount of work that entails, I'm not balking at that, I'm balking on whether or not I have room for it in my budget. On the former front, I dunno, I kinda feel like some of the people in the group would find it a relief to have every other week off from gaming, but I don't want them to feel abandoned either.

I suppose there's some nervousness about trying a new group too; I've been stung by that once or twice, but I don't have to go back if it sucks, so I'm not that worried about it.

I dunno, I'm very conflicted about the whole thing. Gonna try sleeping on it.
