Already contacted the owner of the field I play at, he said it's alright with him and even suggested brands of regulators to look at.
And I know the PSF unit is a gearbox, I looked at it already.
As far as gear goes, I have everything I need to play. Had it for seven years. I may be just another face in the crowd but I'm not an idiot who breaks the rules. Not to mention I've been asked by a company to head a team they want to sponsor I think that should show some credibility on my behalf. Not that anyone on here knows me anyway so that really means nothing...
As for other fields, I don't even know where else to go other than Adrenaline, so right now I'm not concerned about it.
Thanks for your suggestion, though.
