So........................in time does it cause non-sheeting windows to sheet?
?
Matt just wondered how you are getting on after moving to wfp ? Am trad myself and thinking of going over to the other side 
Ok matey, lemme tell ya, its been the best move I ever made, absolutely no doubt about it.
Some guys on here said in time, shortly after going over, you'll have bad days and wish you'd never done it, you'll want to throw it out and go back to the ladder, they were right, those moments came, and lasted all of 10 minutes.
I love it now, I have a real enthusiasm for it, love my job all the more, I find it so much more challenging/rewarding and the money, well, its better than I hoped for sure, oh yess !!
So, Id would say without a doubt, do it. You WILL NOT regret it.
Matt
