Replacing Caps on Maggie X-over

Has anyone replaced the external cap. bank that adds up to 120.3uf? If so what were your results? Should I use one big one, or a series of 3 to 4 that add up to 120uf? The 20.1 model I have uses a series of Solen 250v caps that are metalized polypropelene. They also use 3 tiny .1uf caps as bypass (is this a good idea?) I am just starting to investigate this process so any help would be appreciated, thanks.
