As one who has done the transition i agree with "most" of what NikNak says.
a. It is harder, having to unlearn what you have previously done to control aircraft. No allowances are made for previous experience (in fact sometimes it can hinder you as you revert to what you know when it gets busy)
b. There are still 'secondary duties' to a degree (OK these aren't forced upon you) but it can get you out of controlling for a bit.
c. The money is better BUT not until you qualify (which could take upto 3 years!) Try living as a trainee on the current structure if you have a family or any sort of committments.
Thats my thoughts...
