is there a faster alternative to google sync?

[csawatsky]

I have a couple of users with 1000-7000 contacts, and they are interested in syncing these from gmail to blackberry OTA

I myself use google sync, but with 150ish contacts. After implementing these users, they are finding that their BB is constantly hourglassing I assume trying to process the large sync dataset.

Is there any better way to do this, short of implementing exchange/BES? Maybe even set google sync to sync at 6 hour intervals?

thanks!

How about sync using Desktop Manager? Do they need it to be updated that often? I find my contacts remain pretty static.

they're very contact-centric people (you'd have to be to have that many contacts) so it would be preferable to do it wirelessly. I've resigned myself to the fact that it's just not going to be doable without bes
