I'm guessing most people around here have said this before and will laugh at me for saying it now, but I have NO plans to go that big. But ... I've been wrong before.Just wait until you really get into it. I am in the process of mapping out a PT-1 right now, trying to fit everything I "need" on it. Easily $2K worth of pedals alone, then you've got the board, cables, power supply(ies), etc. It's a deep hole for sure, but damn fun!
Depending on the wireless and if you feel like going into a little DIY, you could mount it under the board. A L6 G30 or G50 could probably fit fairly easily. I've thought about putting my G50 under the Mini quite a bit.
I've seen threads from people who've put G30's under their boards, even Mini's, but I don't recall seeing people put G50's under a Mini. I'll have to do some surfing when I get home from work tonight to see if I can find people who did that. Actually, I do have a G50, it's one of the other pedals I bought that isn't on the board right now. I love using it and being able to move around that freely, but I was getting more real use use out of the other pedals so that one is currently with the other "maybe" pedals. It seemed more of a decadent luxury than something I REALLY needed. Not that I have any plans to sell it.
