Looking at that vidio it would almost seem to be more dangours with off board tanks. On the models that I had a pressure gauge installed the presure would never get higher than 50psi, if you pulled the line off the presure drops to all most nothing with in a few secounds. The on board tanks are far to small to mantian any pressure with the line pulled off, this may have some thing to do with were I live as it rarely gets to 90F in summer.

For those that prefere they off board tanks I am woundering for what reason? I like the on board tank because that is one less thing to drag down to the start box, I did go with off board tank on my Reaction andd did not like that at all.
