I added some 100mg PG base from WL to 24mg Torque. Made some 40mg and some 36mg for use in my eRoll. It bumped up the TH quite a bit but I wouldn't call it harsh. Later I lucked into some Torque concentrate and made some at 60mg to mix with the the 24mg so I would have 36mg without diluting the flavor. Those are the only strong batches I've made and I only use them in the eRoll which doesn't hit as hard as my RBAs. You can definitely tell the nic is there and for me it only takes a few hits to be satisfied.
