In reply to Baz P:
If you have system you are happy with, I'd say stick with it.
However, once you've sorted it, tubeless is very reliable, but it can be painful path.
Last few years, it's been around one/two flats a year for me (really rare and I'm super pissed when it happens). I did 7 enduro races last year, no flats. (nb - some self-seal without you noticing)
I carry a spare tube taped to frame. Small pump and C02 canister. I tried the plugs things, but simpler to just bung a tube in on the rare occasion of a full flat. And yes no real hassle to stick tube in, especially fast with a CO2. Liquid sealant can be messy, but no big deal.
But you've got to want to change to tubeless. If you are being pressured (see what I did there, lol), you'll just resent the bit of faff as you get used to tubeless.
30 is high pressure to me. With tubeless and right tyre combo I can run 16-18 on front and 24-26 on back on 2.4 tyres. And not be afraid of flatting.
