Hello guys , Had my 1st try with MTI hose today , couldn't get the bag to vac down . Pulled everything apart and connected the MTI hose directly to the vac hose and pulled 100% vac ??   What am I doing wrong ? MTI hose didn't seem to let air through ??    Tried the traditional way with spiral and resin break and infusion seemed to go well . I will pop it tomorrow to see what the surface looks like . 

MTI definitely flows less air, it often takes my 5cfm pump a good 5 minutes to pull down a small 30x30cm bag whereas without it that same size bag would be pulled down almost straight away.
