Here's some poop on various disk speeder-upper products with C-Power:

I have no direct experience with C-Power and Fastload, but there was
some discussion about it on the C-Power BBS about a year ago.  The main
points I remember were that you must avoid save/replace in the editor,
and that you must initialize the disk fairly often: disk i0.  Doing it
before and after a save is probably a safe thing to do (there is a
well-defined sequence, but I don't recall what it is).  In case you
didn't know, the "i0" disk command causes the drive to re-read the BAM.
The 1541 ROM normally does this automagically when it detects a new disk
in the drive, but Fastload apparently confuses the 1541 occasionally. 

C-Power 64 works extremely well with 1541 Flash, if you don't mind
making ROM changes to your 1541 and 64.

C-Power 64 and Mach 5 (Mach 128 in 64 mode) seems to have similar
problems as the Fastload cartridge.  I don't know if the disk
initialization tricks help the situation. 

Pro-Line (the makers of C-Power) sell a disk speeder-upper cartridge
that works with C-Power.  I don't recall what it's called.

C-Power 128 and Mach 128 work great together.  I have a 1571 and a 1541,
and it makes that second drive as fast as the first.  I have discovered
one bug in this arrangement, however.  Normally, when you attempt to run
a program that is already in memory, the program will run without
reloading it from disk (this feature is most useful to load a program
from one disk, change disks, and then have the program use the new disk
for data). With Mach 128 enabled, I've found that the shell always
reloads a program from disk.  Fortunately, it's not a serious problem
with two drives. I haven't found any other compatibility problems so
far.

I hope this information has been useful.
