Hi Henry .. yeah, I think keeping a bit of your own at the back is good to avoid that `lift` which can happen ....mine is very thin at the back, but I`m going to keep about an inch of it... I`ll let the system hair down a little longer over it, [when it arrives soon I hope] I`ll then allow my own to come down longer `under`it ...so in the event I tilt my head forward, anyone looking at the back won`t notice the `difference`--that`s the plan anyway !!:-) I think your approach/idea is good....maybe those who have `gone before`us will chime in here!
Paul.
