I haven't played at many but i have played at a few non commercial fields with friends
Midway is awesome the staff are great and they have lots of fields. Their saftey talk before each match is great and funny. Although they usually dont let people play harder games like fox and hound unles requested but still playing the originals is always fun.
ZThey rent top of the line tippman 98 customs and even the begginers have fun. The refs are always fun and let you and your group choose where to go and what to play.
One of their best features is they supply a hotdog with each rental package.lol. I would by far rate this field top on the island and possibly B.C. ;)
