Hi Sandy,

Just wanted to say that, if I were you, I'd get on Google and start reading as much as you can about them both. Word of advice, when searching, put in a date, like "2006" - you'll need the most recent info you can find.

Obviously it'll be helpful to get reactions from the members here, but you need to know as much factual information as poss, and then apply it to your very particular set of circumstances.

Haven't had either block myself; but I know for sure some people here have had the SGBs, at least. Good luck with them!

all the best
