Sorry Russell - I didn't see your post before bidding - I was the high bidder for these. I usually give way to members of forums I participate on (or at least ask before bidding).The seller has yet to respond to shipping charges, but if you have been waiting quite some time for these I can cut a deal for what I bid (only a little above what you bid). I feel a bit bad about getting in the way.
And yes - these drivers should be OK - they don't go far low, so Xover is a bit of an issue.
