I really like both outdoor and indoor fields, but thats very vague, i really like urban outdoor fields that have CQB fighting in it as well. I dont like alot of the CQB fields here, for example splatters, since the ground in general isnt that great for playing. The sand really pisses me off. i can deal with the paint on the walls but the sand just prevents one from playing properly. You cant run properly without tripping on a mound of sand and it feels awkward.
I think the best field i played in so far is Wasaga Paintball, good mixture of urban type fields with forest.
Overall i still miss playing airsoft back in Hong Kong
they have some of the best CQB fields there
