Ideally, you should use blades that accept RJ-21 connectors (aka
Telco connectors). These let you terminate 4 25-pr cables at the
switch rather than 48 4-pr cables.
For the 6500, the blade is the WS-X6548-RJ-21:

I've used the RJ-21s and personally, I wouldn't do it again. If you lose a
pair, you
have to replace the whole cable <all custs> whereas if you lose a cable on
the rj-45, you have to replace a cable<1 cust>.
As far as making cable management work:
Sweep Left Sweep Right
[ <--- 1-2-3-4-5-6-7-8-9-10-11-12 ] [ 12-10-9-8-7-6-5-4-3-2-1--> ]
I always cut em down the middle and take 'em left or right to the cable way up
to the ladder tray.
