Yokomo YZ4 to go with my YZ2

[Whoopner]

I have a YZ2 which I love but the temptation to get a YZ4 is creaping over me. My outdoor club is using more and more 4wd buggies especially during the winter and a new club I've just been to who run indoors are mainly 4wd.

I'd wanna keep the YZ2 especially for the summer but what are people's thoughts on swapping between 2wd and 4wd? This will be my first 4wd buggy if I get it so how can I expect the difference between the cars to feel?

With that question in mind what tyres do people recommend for indoors and out on 4wd

I use currently on the 2wd yellow stagger or cut staggers on the front if I'm indoor or out. On the rear yellow mini pins for indoors or outdoors generally yellow mini spikes and ballistic greens if wet.
