FIGE separation of YACs / yeast chromoosomes

we are currently trying to use FIGE to isolate YACs of mean size 300 KB
(range 100 KB to 1 MB) , in order to subclone. We are having real problems
identifying conditions that give reproducible results, seperate bands etc.

Please could anyone recommend:

% and type of agarose
run temp
sample loading techniques (plug vs liquid etc)
switching conditions

that give reliable results in the 100Kb to 1 MB range.

Thanks in advance,
