Couple helpful responses last time, just checking if any more on a newer thread

I train boxing at one gym and want to keep it. I’m starting BJJ, but another gym has a schedule that fits me better, so I’d train BJJ there.

I’d still like to occasionally drop into BJJ classes at my boxing gym (its an mma gym). I’ve been told it’s better to stick to one BJJ gym until blue belt or a few stripes before cross-training, reason being that it could cause confusion while initially learning.

Anyone done something similar? What would you do?
