Thank you guys for all the advice and opinions. It has made a difference. Yesterday I was all for doing it but I've decided not to go for the type rating + line training option.
What I will do is do some structured hour building to keep my skills in check.
I think just renting a plane on my own would be damaging because I'm not really going to teach myself and my bad habits would become really bad ones.
Flying with an instructor who knows your situation and knows what skills you should be developing would be alot more beneficial.
Maybe throw in a sea plane rating for some fun.
I think patience is the key. It will happen eventually. best of luck to all of you
Thanks again
Just out of interest does anyone know why the 737type rating and line training soooo much cheaper than the a320
