Delta force are the equivalent of tescos in paintball. The big corporation
This means they have the backing to invest highly in sites
Each site is as good as the manager and staff
Delta force are not as bad as a certain other company that used to sell tickets claiming they can be used at numerous sites. Delta force tickets are sold on the street under the guise of IPG
They are genuine in that they are for the sites they say, and you do make a saving if you buy from the seller compared to IPGs website prices. But noone would pay IPG website prices
Skirmish are more of a collective of sites, each individual site being independant
If the site does not have the big corporate investment funding they may still have originality and keep updating / changing zones
No matter what the company, phone the site and ask what price you will pay, particularly with preordering your paint.
Don't believe anyone who says '£x for entry, all gear and your 100 paintballs', unless they stress plus paint throughout the day as you require, and give a fair guide on a days play
Note the punter rates paid for all are higher then most people on here will pay for walkons/tournaments/scenarios. But it's for a different customer with a differnent experience and is how sites stay in business and pay the overheads
