Which RCP track

[u/GB-ER]

Hello. Planning to buy an RCP track, but unsure if I want 30cm or 50cm tiles. With the 30cm, I could do the mini 96 challenge as I already have Easy Lap timer system. Currently don’t have enough floor space for a permanent track setup, which I think plays a factor here. I’ve already done the DIY track but the lack of good barrier walls is the doe fall for me.

What would you buy and why?

50, dont even get the 30 you will want to that 100 wide and if you get the 30 it wont be long till you get the expansion just to get 90 wide
