Thanks bud.
Yes, the crotch area is what we recommend. If you decide to substitute then use Quick Fix, its the best on the market and comes with its own temperature strip, along with a hand warmer to keep you in the right temperature range. All the information you need is in the Substitution thread at the top of the drug testing forum.
